ProXR Expandable Board
This Board includes the XR Expansion Port for adding additional relays to the board. The XR Expansion Boards can be added to control up to 256 relays on this board!
The ProXR SPDT Relay Board
ProXR RelayWe'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!
Easy Software DevelopmentMost 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 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.

Base Station SoftwareBase 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.
ProXR Enhanced Firmware InstalledThis 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.
SPDT Relay InstalledThis device has SPDT relays installed. SPDT Single Pole Double Throw Relays have three connections - Common, Normally Open, and Normally Closed. When the relay is off, the common is connected to the normally closed connection of the relay. When the relay coil is energized, the Common swings to the Normally Open Connection of the Relay. You can wire the device you are switching to either the Normally Open or the Normally Closed position using screw terminal connections. The maximum guage wire the terminal can handle is 14 ga but we have used up to 12 ga solid core for several applications with no issues.
2-Million CyclesProXR 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 RequirementsApplying 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 CompliantThis 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.
Add Relays as Your Needs GrowThe ProXR series controllers are expandable up to 256 total relays. The controller is fitted with an XR Expansion Port where you can add expansion boards to this relay. Expansion boards can be added until you reach 256 total relays. The Expansion Boards get their logic from the main board and will require 12 VDC power. Expansion boards do not need to be the same relay amperage as the main board or other expansion boards.
Read Analog SensorsThis ProXR controller offers a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control. This board is equipped with 8 inputs that can accept an input from 0 to 5 volts. The boards AD8 Command Set is used to read the analog voltages and converts the 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.
16 User-Programmable TimersThe 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.
5-Year Warranty/Money Back GuaranteeProXR 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 SuppressionPerhaps 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.

ProXR Command Set
The ProXR Command Set is the industry leading command set for controling relays! You can find the complete command set in the ProXR Quick Start Guide.
The ProXR Command Set
IntroductionThe 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 doesnt 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.
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 BankThis 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:|
|Hex Values||0xFE||0x00 - 0x07||0x01 - 0x07|
Turns On Relays in the Currently Selected Relay BankThis 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:|
|Hex Values||0xFE||0x08 - 0x0F||0x01 - 0x07|
Read the Status of Relays in the Currently Selected Relay BankThis 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:|
|Hex Values||0xFE||0x10 - 0x17|
|Receive Byte:||Decimal:||0 or 1|
|Hex:||0x00 or 0x01|

AD8 Command Set
A/D Inputs can accept a voltage from 0 to 5VDC. You should NEVER exceed this voltage range! You can find the complete AD8 Command Set in the AD8 Quick Start Guide.
The AD8 Command Set
Reading Switches/Variable Resistance SignalsThis 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 RelaysProXR 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 ConnectionsAD8 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 SetThe 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 ChannelsThis 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)|
|Hex Values||0xFE||0x96 - 0x9D|

Base Station Software for AD8
Base StationBase 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 InputsThe 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 ControlRelay 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.

Time Schedule ControlRelay Timer Software allows you control each relay independently from a time schedule you create! The software can be installed on a server or PC and uses the computers time for an accurate relay control.
Control relay in recurrent time sequenceThanks to protocol of ProXR & ProXR Lite boards it is possible to update 8 relays at one time. If speed is a requirement it only take about 30 ms to update 8 relays. In multiple relay applications Relay Timer calculates all relays’ status together, even though each of them work separately.
Take Manual ControlYou can take manual control of any relay at any time to interrupt the schedule and control a relay. Automatically switch back to Auto Mode and resume the schedule manually or set a fixed time to return to the schedule.
Time Sequence ControlQuicktimer Software supports turning on/off each relay automatically during the predetermined duration. First set the duration that you want the sequence to be active. Time periods can then be set where the relay is energized within the set duration.
Control Relays by Time DurationQuick Timer is a software program specifically developed for the relay boards on our site. The software will allow you to control the duration the relays will be energized. This software is not designed to control relay at a specific time of day but rather a time duration. The time sequence is manually started and can run through a set sequence and stop of be set to loop until manually stopped.
Control Within a Predetermined DurationQuick Timer Software supports controlling each relay automatically during the predetermined duration. A duration can be set first then each relay on the board can then be controlled with their own time sequence within the set time duration.
