Wireless Relay 16-Channel 30-Amp with UXP Port

Wireless Relay Control

Long Range Wireless Industrial Mesh

Long-Range Wireless Mesh networking is the ONLY communications technology NCD recommends on the factory floor, operating at a safe 900MHz.  Mesh technology will hop data from one location to another to reach its intended destination, users do not need to do anything other than make sure wireless modules stay within hopping range of each other.  We use the Digi 900HP-S3B module in many of our products, as this is the best industry has to offer.  With a 2 mile range between modules and up to 8 hops, it is possible to cover 16 miles of wireless territory using this technology.  Using high-gain antennas, this module is capable of communicating to a remote module up to 28 miles away!  Please note that data hopping only works between live devices.  Data will hop from sensors to gateways and modems.  Data will also hop between gateways and modems.

Long Range Wireless

XBee-PRO 900HP embedded modules provide best-in-class range wireless connectivity to devices. They are easy to setup and use, reliable and capable of transmitting a ling distance.  You will need an 900MHz modem that plugs into your USB port of your computer to talk any number of boards with a standard range of 2-miles and up to 15 miles.  You can choose the distance of the module installed at checkout.

XBee-PRO 900 RF Module

This board is equipped with an 900HP Module.  The XBee-PRO 900 RF module is ideally suited for less power-hungry, low-latency point-to-multipoint networking applications.  Capable of point-to-point, peer-to-peer and point-to-multipoint networking, The XBee-900 modules have a higher selectable transmitting power of 250mW.  This higher TX power allows for line-of-sight range up to 28 miles with the right antenna.  It is ideal for solutions where RF penetration and absolute transmission distance are paramount to the application.

Line-Of-Site Operation

As with any wireless technologies, for optimal performance it needs to be line-of-sight.  In other words the antennas of the board and modem must "see" each other to get the optimal range or even be able to communicate at all.  Mounting slots on the modem make it easy to attach to a wall to allow for line-of-site operation.

Standard Range Antenna

The XSC900SR Standard Range Antenna (distance of 2 miles) is included with the price of the controller.  The included antenna is a 6" whip antenna with an RP-SMA threaded connection.  The antenna will screw directly onto the wireless module.  NCD has tested this device at 2 Miles with excellent results using smaller antennas than what would be required to achieve the 28-Mile range achieved by the manufacturer.  All range tests are conducted in clear line-of-sight installations.  It is not possible for us to accurately predict range prior to purchase.  We cannot predict range inside buildings, using google map images, or predict interference that may be present at your location that would prohibit proper operation.

900MHz Wireless Modem

Plug the UXSCMSR_ZIGMO short range modem or UXSCMLR_ZIGMO long range modem into the USB Port of your computer.  The modem will mount as a COM port on your PC.  Open the COM port and start sending data to the modem.  The modem will forward your data to all Wireless XSC compliant devices within range (it is also possible to speak to a specific device when other controllers are in range).  The modem is also available at checkout.
XSC Modem

Sending Commands

Base Station Software is available at no charge to get you up and running fast (more on Base Station below).  Once powered up, the controller waits for a ProXR command.  A command consists of a few bytes of data in numerical format usually between 2 and 6 bytes.  Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command.

The ProXR Relay Board

ProXR Relay

We've looked at the interface now let's take a look at the board design and programming.  The ProXR series controllers are manufactured by hand for a highly accurate and reliable design.  Equipped with the XR Expansion Port additional relays can be easily added.  Fully tested before they leave the production facility each ProXR controller is ready to stand up to rigorous demands from heat, cold or vibration.  The best test of all is the numerous boards in the field from customers all over the world in all sorts of conditions.  Take it from us, these controllers will hold up!

UXP Expansion

UXP is a standardized data port, specifically for the purpose of speaking to various expansion modules.  This controller is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules.  You will find the UXP port on models with UXP in the part number.

UXP Expansion Modules

UXP Expansion Boards have no on-board brains.  They are entirely reliant on the brains of a "master" device.  A master device is an NCD controller with a UXP expansion port and a microprocessor of some kind.  Most master UXP devices have on-board relays.  If you need to add A/D, Contact Closure Inputs or Digital Potentiometers just plug in the appropriate expansion module.  You cannot daisy chain different types of modules to the same controller however.  In other words if you plug in a potentiometer you will not be able to plug a contact closure or A/D module also.  For controllers that are equipped with a UXP Expansion port (and are suitable master devices for UXP Series Expansion) simply look for UXP in the part number.  All UXP Expansion Modules have an input and an output so you can simply daisy chain the boards together until you reach the number of contacts you are looking for.

Summary of UXP Modules
• Compatible with UXP Series Controllers ONLY
• Not a stand-alone controller - MUST be used with a UXP Series Controller
• Add Contact Closure Inputs
   - up to 256 Inputs
• Add Analog to Digital Inputs
   - up to 48 Inputs
• Add Digital Potentiometer Outputs
   - up to 256 Outputs

XR Expansion Port

Most UXP controllers (Master Devices) have an XR expansion port and therefore can accommodate XR Expansion Boards.  Typically the XR Expansion port is used to add relays to the main controller (Master Device).  Like the UXP Expansion boards the XR Expansion Boards have no on-board brains.  They are entirely reliant on the brains of a "master" device.  When you run out of relays, just plug in an XR expansion board that is equipped with the kind of relays you need.  You can add up to 256 relays including the relays that are on the main controller (Master Device). All XR Expansion modules are compatible with each other so if you want to add different types of relays you can.  For controllers that are equipped with an XR Expansion port (and are suitable master devices for XR Series Expansion Controllers) simply look for PROXR in the part number.

Using XR and UXP Together

If you select a board that is equipped with both XR and UXP port you can use both ports simultaneously.  This allows you to add and control more relays through the XR port plus add A/D, Contact Closures or Potentiometers to the same board through the UXP port.  This can all be controlled through the same virtual COM port on your computer.  These Expansion Boards can be purchase with the controller or purchased at a later time when you have a need to expand.  To use both ports together you will need to select a controller that has UXP and PROXR in the part number to have bothports available on the controller (Master Device).

ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set.  The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market.  The list of commands and parameters this board is capable of is extensive.  ProXR Enhanced is the newly released enhance version of the ProXR Firmware with more commands, more functionality and better control than ever before!  For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.

Base Station Software

Base Station Software was designed to help you learn the ProXR command set.  Explore ProXR features using it's Graphical User Interface.  Watch data bytes flow to and from the board, so you easily understand the command execution process.  There is no faster or easier way to learn how to automate than Base Station, as it was designed to work with the complete array of communication modules.  Base Station software supports every feature of this device - no other controller manufacturer even comes close to offering this type of software. 

SPST Relay Installed

This device has SPST relays installed.  SPST Single Pole Single Throw Relays simply connect two wires together.  The Common (COM) is the  moving part of the relay that comes in contact with the Normally Open (NO) when the coil to the relay is energized.  Wiring is done directly to the Relay terminals using a common 1/4" quick disconnect terminal.  To the left is a picture of the connector that will connect to the relay.

2-Million Cycles

ProXR series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board.  With a 5-year warranty and a money back guarantee you have nothing to loose!  Place your order now, while everything is in front of you.

Essential Power Requirements

Applying Good clean power to the board is essential for the operation of the board.  Not only for the switching of the relays but the firmware that processes the commands.  Without good steady clean power from a regulated power supply the board simply will not function correctly.  All boards on the site require 12 VDC power.  The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board.  The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector.  We also carry an international power supply with interchangeable adapters for international customers.

This Board is RoHS Compliant

This board is led free and RoHS Compliant.  If your requirements are for RoHS compliant parts this board is manufactured with RoHS compliant led free parts and solder.

16 User-Programmable Timers

The ProXR Series controllers have 16 user-programmable timers. Each independent timer can be assigned to any relay, and can be programmed to hold the relay in the On state, or to pulse the relay at the end of the timer.  The ProXR timing features are ideally suited for Watchdog, Keep Alive, and Server Reboot applications, as well as sprinkler systems, gate openers, and lighting applications.  Relay Timing Features support two modes of operation: Duration and Pulse. Duration timing is ideally suited where a device should be activated for a period of time. Pulse timing mode is designed specifically for server reboot applications, whereby, if the timer is not reset periodically by your software, the timer will run out and reboot your computer.

Easy Software Development

Most of our customers write their own program for controlling these devices. Since you can use almost any programming language, you can use one that is most familiar to you so you don't have to learn a new language.  These boards support the Serial Port Profile, meaning they will mount to the computer as a virtual com port. This makes it very easy to send commands to the device.

Plug-In for Visual Studio

The NCD Component Library is a plug-in for the Visual Studio 2005/2008 that greatly simplifies the communications to the NCD product line. The samples can be run in Visual Studio and full customization to your needs.  Over 40 samples included with this free download!  Component Library.

5-Year Warranty/Money Back Guarantee

ProXR Lite series controllers are guaranteed against manufacturing and functionality defects for a full 5 years!  Not to mention a 30-day money back guarantee!  If for any reason you are not happy with a relay purchased from Relay Pros, simply return it within 30 days and we will give you your money back!  Controllers that are damaged by our customers will not of course be warranted under any circumstances. 

Induction Suppression

Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer.  Controlling a inductive load using this relay board requires an induction suppression capacitor for each relay being used.  The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay.  Without this capacitor, the lifespan of the relay will be greatly reduced.  Induction can be so severe that it interferes with the logic of the board, causing relay banks to shut down unexpectedly.  For more information view our Induction Suppression Video.

• Programming Flexibility: Compatible with nearly any programming language.
• User-Friendly Software: Free software available for non-programmers to easily control relays without coding.

Introduction

The ProXR Series Controllers allow you to control up to 2048 relays depending on your controller model.  Relays are divided into groups of 8 called banks, and are addressed by their bank number.  For instance, a ProXR series controller with 32 on-board relays has four on-board banks, the on-board relays respond to bank values of 1-4.  If you use the XR Expansion port to add another bank of 24 relays, then you will need to specify bank values of 5-7 to control the extra relays.  The firmware doesn’t actually know how many relays are attached to the relay controller, it is up to the user to define how many relays are attached to the controller using Base Station Software.  The ProXR CPU will assume you have connected the maximum number of supported relays to your controller.  In the ProXR Quick Start Guide, you will see two commands that appear to do the same thing, for example:

  254 0-7 Turn Off Individual Relays
  254 100-107 Bank# Turn Off Individual Relays in Bank
  254 8-15 Turn On Individual Relays
  254 108-115 Turn On Individual Relays in Bank
  254 16-23 Get the Status of an Individual Relay
  254 116-123 Bank# Get the Status of an Individual Relay in Bank
While the outcome is the same, these commands function in slightly different ways.

For instance:
  254 8 Turn On Relay 1
To make this command work, you will send a 254, then a 8 to activate a relay. By default, relay bank 1 will be affected by this command. However, you can redirect this command to a different relay bank using the following command:
  254 49 2  Direct Commands to Relay Bank 2
Then you can send:
  254 8 Turn On Relay 1 in Bank 2

Here are a few more Bank Specified Examples:
  254 49 1 Direct Commands to Relay Bank 1
  254 8 Turn On Relay 1 in Bank 1
  254 49 2 Direct Commands to Relay Bank 2
  254 8 Turn On Relay 1 in Bank 2
  254 9 Turn On Relay 2 in Bank 2
  254 10 Turn On Relay 3 in Bank 2
  254 49 3 Direct Commands to Relay Bank 3
  254 8 Turn On Relay 1 in Bank 3
  254 11 Turn On Relay 4 in Bank 3
  254 12 Turn On Relay 5 in Bank 3
  254 13 Turn On Relay 6 in Bank 3
  254 14 Turn On Relay 7 in Bank 3
  254 49 0 Direct Commands to All Relay Banks
  254 8 Turn On Relay 1 in All Relay Banks

This command structure has the advantage of being very fast and efficient. However, if power to the controller is ever lost, commands will automatically be directed to bank 1 when power to the controller has been restored. This command methodology is generally advisable for ProXR controllers with 8 or fewer relays. When working with more than 8 relays, we generally advise users to use Bank Directed commands as shown in the following examples.

Turns Off Relays in the Currently Selected Relay Bank

This command will control the Off status of specified relays in the Currently Selected Relay Bank.  This command has optional parameters <1-7> for controlling the Off status of the remaining relays, 1 being the next relay in sequence, 2-7 being all possible subsequent relays in the selected relay bank.  A value of 0 refers to the first relay in the specified relay bank, 7 being the 8th and final relay of the selected Relay Bank. This command sends byte value 85 back to the user when the operation has been completed.

Send Bytes:	Byte 1:	Byte 2:	Byte 3:
Function:	Command	Command	Optional Parameters
Decimal Values:	254	0-7	1-7
Hex Values	0xFE	0x00 - 0x07	0x01 - 0x07
Receive Byte:	Decimal:	85
	Hex:	0x55

Turns On Relays in the Currently Selected Relay Bank

This command will control the On status of specified relays in the Currently Selected Relay Bank.  This command has optional parameters <1-7> for controlling the On status of the remaining relays, 1 being the next relay in sequence, 2-7 being all possible subsequent relays in the selected relay bank.  A value of 0 refers to the first relay in the specified relay bank, 7 being the 8th and final relay of the selected Relay Bank.  This command sends byte value 85 back to the user when the operation has been completed.

Send Bytes:	Byte 1:	Byte 2:	Byte 3:
Function:	Command	Command	Optional Parameters
Decimal Values:	254	8-15	1-7

Receive Byte:	Decimal:	85
	Hex:	0x55

Read the Status of Relays in the Currently Selected Relay Bank

This command will report the On/Off status of Relays 0-7 in the Currently Selected Relay Bank.  This command sends byte value of 0 of 1 back to the user when the operation has been completed, 0 reporting an Off status and 1 reporting an On status.

Send Bytes:	Byte 1:	Byte 2:
Function:	Command	Command
Decimal Values:	254	16-23
Hex Values	0xFE	0x10 - 0x17
Receive Byte:	Decimal:	0 or 1
	Hex:	0x00 or 0x01

A/D Inputs

AD8 Analog Input Usage Notice

Analog inputs should never have voltage applied when the controller is powered down. If your application requires voltage to remain on an input, add a 220-ohm current-limiting resistor to each channel to protect the controller from damage.
Keep all analog inputs within the 0 - 5VDC range - exceeding this limit can permanently damage the on-board CPU. Most inputs include a 10K pull-up or pull-down resistor to keep the line stable when unused, but note that this resistor may introduce a slight bias in readings for certain sensors.

Software Options

Not a programmer and these boards look intimidating? Don't worry. Powerful software tools make it easy to get connected, discover attached devices, monitor inputs in real time, and control relays without writing a single line of code. Create on-screen buttons, desktop meters, timed events, and automated actions that respond to inputs, schedules, or system conditions - all from an intuitive graphical interface.

Time Control Software

Relay Timer

Time Schedule Control

Relay Timer software works with all ProXR and ProXR Lite relay controllers and supports every available interface - USB, wired, wireless, and network. No matter how your board is connected, Relay Timer communicates seamlessly to deliver reliable, scheduled relay control.

---

Precision Scheduling Using Your Computer's Clock

Relay Timer uses the computer's system clock to maintain accurate, drift-free timing. This ensures relay actions stay perfectly synchronized with other applications running on the same machine, such as time clocks or automation software.

A high-resolution timing engine - similar to those used in multimedia applications - provides timing accuracy down to 5 - 10 milliseconds, making Relay Timer well suited for real-time and precision-based control tasks.

---

High-Speed, Multi-Relay Control

Relay Timer can update up to eight relays simultaneously using the ProXR and ProXR Lite communication protocol. When speed matters, all eight relays can be updated in approximately 30 milliseconds.

In multi-relay applications, Relay Timer calculates the state of all relays together, even though each relay operates independently. This ensures fast, coordinated, and predictable behavior across complex schedules.

---

Take Manual Control

At any time, you can manually take control of a relay to interrupt the active schedule. Resume automatic operation instantly or set a specific time for the software to return to scheduled control - ideal for maintenance, testing, or temporary overrides such as school bells for assemblies.

---

Quick Timer Software

Compatible with ProXR & ProXR Lite Boards

Quick Timer software works with all ProXR and ProXR Lite relay controllers and supports every available interface, including USB, wired, wireless, and network connections. The software automatically communicates with your board regardless of how it's connected, making setup quick and straightforward. Designed for responsive, duration-based control, Quick Timer delivers fast, reliable relay operation for timed sequences, test cycles, and repeatable automation tasks.

---

Duration-Based Relay Control (Not Time-of-Day Scheduling)

Quick Timer is designed for applications where how long a relay is energized matters more than what time of day it activates. Instead of using the computer's clock, Quick Timer runs sequences based on a defined time duration.

A sequence is manually started and can:

• Run once and stop automatically, or
• Loop continuously until manually stopped

This makes Quick Timer ideal for test cycles, timed processes, burn-in testing, and repeatable automation routines.

---

Flexible Time Sequences Within a Single Duration

Quick Timer allows you to define a total run duration first. Within that duration, each relay can follow its own independent on/off timing pattern.

Example: 30-Second Sequence

• Relay 1 turns on for 5 seconds, then off for 5 seconds
• Relay 2 turns off for 5 seconds, then on for 5 seconds
• Relay 3 turns on for the first 10 seconds, then off for 20 seconds
• Relay 4 remains off for 10 seconds, then turns on for 20 seconds

All relay actions are calculated and executed automatically within the defined time window.

---

Independent Control Per Relay

Each relay can be configured with its own timing behavior while remaining synchronized within the overall sequence duration. This allows complex, coordinated relay patterns without requiring scripting or programming.

---

Manual Override at Any Time

Manual control is always available. Interrupt the active sequence to toggle any relay as needed, then return to automatic operation immediately or at a user-defined time.
