Long Range Wireless Relay 1-Channel 30-Amp ProXR Lite

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 Lite SPST Relay Board

ProXR Lite Relay

In this tab we'll take a look at the board design itself.  The ProXR Lite series controllers are machine manufactured for a highly accurate and reliable design.  Fully tested before they leave the production facility each ProXR Lite 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!

Not Expandable

Unlike it's big brother, the ProXR Series, the ProXR Lite series controllers are NOT expandable. The firmware still thinks 256 relays are available but the relay portion of the controller only responds to the first 1, 2, 4 or 8 relays in Bank 1.

Full ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set - it's just not expandable.  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. 

Easy Software Development

Most of our customers write their own program for controlling these relays.  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 board.  Not a programmer, check out N-Button!  Software that allows you to configure buttons to control relays and read the status of those relays without programming using point-and-click action.  Click Here for More

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. Learn More

Read Analog Sensors

All ProXR Lite controllers offer a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control.  Read and control from 8 sensors per board from 0 to 5 volts (0 being a dry contact)!  A/D inputs are ideal for reading the on/off status of switches, connect a switch between input and ground and software may then be used to monitor the contact closure status of the switch.  AD inputs can also be used for reading variable resistance signals, the board will then will return a value between 0-255.  Click the grey Data Sheets tab above and look for the AD8 Quick Start Guide to see the full AD command set.

SPST Relay Installed

This board 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 right 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.

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.

Break-A-Way Tabs for a Smaller Design

The ProXR Lite relays have a great feature where space is a premium - Break-A-Way Tabs. The Break-A-Way Tabs allow most boards to fit in an optional undrilled plastic enclosure.  Snap off the Break-A-Way Tabs and you have a controller with a smaller profile when you need to fit in a tight space.

30-Day Warranty/Money Back Guarantee

ProXR Lite series controllers are guaranteed against manufacturing and functionality defects for a full 30 days!  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.

The ProXR Command Set

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
Hex Values	0xFE	0x08 - 0x0F	0x01 - 0x07
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

Base Station Software

Base Station Software was designed to help you learn the ProXR command set!  No other relay board manufacturer even comes close to offering this type of software!  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 all the communication modules we offer!  You only need a Windows 8 or 10 Computer to Run Base Station. 

Base Station Features

There are some useful features to look for when using Base Station Software to control, test, or configure your device:

• At the bottom left corner of each window there is a link to relevant documentation for your device
• In the Control Command Set Window, and many others, there is a MORE or LESS option at the top right corner.  Selecting MORE allows you to view specific communication details.
• All the functions of the command set are available as a point-and-click interface plus you can see the command that is being sent to the board!

The AD8 Command Set

Reading Switches/Variable Resistance Signals

This board is equipped with 8-Channels of 8/10-Bit Analog to Digital Converters, capable of reading analog voltages from 0 to 5 Volts DC.  The ADCs on this controller allow monitoring of external sensors or contact closure input detection.  Connect external temperature sensors, light sensors, current sensors, buttons, switches, or anything else that generates a 0-5VDC analog or contact closure output.  With 8-bit resolution, analog inputs will convert 0-5 Volt signals into a value from 0 to 255.  With 10-bit resolution, values of 0 to 1023 may be measured.  Input resolution is software selected.  Simply ask the controller for the analog value of each input, and the controller instantly responds.

Analog Inputs Controlling Relays

ProXR AD8 controllers allow you to map analog inputs for direct control of on-board relays.  Inputs can be configured to flash relays, turn relays on or off, toggle the relay state, send push notification data, and much more.

Analog to Digital Connections

AD8 Series controllers allow users to monitor sensors and switches.  A/D inputs should never be left “floating,” which simply means all inputs MUST connect to something (such as a voltage or ground).  To prevent inputs from floating, a 10K Resistor connects each input to +5 or Ground using the pull up/down jumper.  While this 10K resistor does slightly interfere with the signal, its benefits far outweigh the consequences of leaving inputs floating.

AD8 Command Set

The AD8 Command Set is used to read analog voltages on controllers equipped with an 8-Channel 8/10-Bit Analog to Digital Converter.  The AD8 Command Set converts a Voltage from 0 to 5 Volts DC into numeric value.  The AD8 Command Set supports 8-Bit Analog to Digital Conversion, which converts 0-5VDC to a numeric value from 0 to 255.  The AD8 Command Set also supports 10-Bit Analog to Digital Conversion, which converts 0-5VDC to a numeric value from 0 to 1023.  Since 10-Bit Values must be communicated using two bytes, the following formula must be used to reconstruct the 10-Bit Value:
10BitValue = (MSB*256)+LSB 'Converts 2 Bytes into a Value from 0 to 1023

Reads the 8-Bit Analog Input of Channels

This command will read the Analog Input of Channels 1-8 and return an 8-bit value for each.

Send Bytes:	Byte 1:	Byte 2:
Function:	Command	Parameter (Channel 1-8)
Decimal Values:	254	150-157
Hex Values	0xFE	0x96 - 0x9D
Receive Byte:	Decimal:	0-255
	Hex:	0x00-0xFF

Base Station Software for AD8

Base Station

Base Station will allow you to read the inputs and will even show you the commands being sent from Base Station so you can use them in your own programming. 

Relay Activator and Analog Inputs

The Relay Activator control panel allows analog inputs to directly control relays!  Simply connect the analog inputs to buttons or switches and trigger basic relay on or off functions to take manual control of the on-board relays.  The Relay Activator control panel allows you to define 8 functions for each of the 8 inputs.  Functions include turning relays on or off, toggling the state of relays, momentarily flash a relay, momentarily toggle the flashing function of a relay, turn all relays on, turn all relays off, and push notification events.  When push notification events are configured, the controller generates a packet of data every time the inputs change state.

Relay Activator for Manual Control

Relay Activator is great for applications where computer control is used but manual control is necessary at times.  Buttons or switches can be used to take manual control of any of the relays.  You will have the ability to turn a relay on with a computer and turn the relay off with the manual switch!  Download the Relay Activator Quick Start Guide here: in the AD8 Relay Activator Quick Start Guide.

Create Desktop Meters

Using N-Button software desktop Meters can be created for real time level readings of a sensor connected to the AD8 inputs!  "It's like having a meter right on your desk for constant monitoring".  Meters can be created for temperature sensors, moisture sensors, light meters and others as long as their output is between 0 and 5 volts.  Create a live at-a-glance determination of the sensor.  There are 8 inputs on the board so you can create a meter for each of the input and label them, our meter here is labeled Soil Moisture.  Best of all the increments on the meter can be fully customized to fit your needs.  N-Button Lite and N-Button Pro can be purchased at checkout.

AD8 Analog Input Usage Notice

Analog Inputs should not have a voltage present when powered down.  Use a 220 Ohm current limiting resistor on each input to prevent damage to the controller if voltage will be present on the analog input when this controller is powered down.  Do not exceed 0 to 5VDC on any analog input or the on-board CPU will be damaged.  Most analog inputs include a 10K Pull Up/Down resistor to help keep the inputs quiet when not in use.  This 10K resistor may slightly bias the readings of some sensors.
