The Most Powerful Command Set Available Anywhere
Add Contact Closure, Potentiometers & Analog to Digital Conversion Modules
ProXR - The Most Powerful Relay Control Available!
This ProXR controller is built with the most powerful command set available anywhere. Simply put, ProXR is a standardized set of commands for controlling relays. This controller is also equipped with a UXP Expansion Port for adding capabilities beyond basic relay control specifically for the purpose of speaking to various expansion modules. Where the XR Expansion port allows you to add additional relays to the board, the UXP Expansion Port allows you to add functionality to the board. With the UXP Expansion Port you can add Digital Potentiometers, Contact Closure modules and Analog to Digital Expansion Modules to this board. We offer a complete line of UXP expansion modules to add to this controller to collect data and process data by custom software that you develop. The applications are limitless and the data that you receive such as A/D Sensors or Contact Closures can easily activate relays when specific levels are reached. See more on our UXP Expansion Page.
Once powered up, the relay controller waits for a command. A command consists of a few bytes of data. 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. You can send commands to activate relays, deactivate relays, control all the relays at one time, plus you can send commands that tell a relay to turn on for a few seconds, minutes, or hours. You can assign 16 timers to any of the 256 relays, and set the timers to go off after the duration has expired. Look at the ProXR Command Set to see the full list of commands available.
The features list of the ProXR series controllers is extensive. Our ProXR Software helps get you acquainted with the powerful command set. To download, look for the ProXR Software in the Resources section to the right and bottom of this page. The ProXR Manual and the mechanical drawing with dimensions and hole layouts can also be found in the Resources section.
Connect this board to the USB port of your computer using a USB to Serial adapter.

ZRS-AB Both! |

Choose the connection that fits your needs. The ZRS-A connection is recommended for applications where hard wiring directly to the board is needed. ZRS-B has the fill 9-Pin RS-232 connector on the board. The ZRS-AB Has the fill 9-Pin connector but is is located off the board for applications where the board may be place inside an enclosure an the RS-232 connector needs to reach to the side of the enclosure. You can choose one of these connection options at checkout. |

Out of the box, the ProXR series controllers are ready to control 256 relays. You may not have 256 relays just yet, but if your application grows, then the controller is ready to grow with you. The ProXR series controllers are built from the ground up to be expanded. When you need more relays, the XR Expansion port will allow you to add another bank of relays (any kind you need), with programming changes taking minutes instead of hours. No complicated protocols, just simplicity, built into the controller from the very beginning.
This controller is equipped with both XR and UXP ports and 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 this 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.
If you need to add capabilities beyond basic relay control to your application, then you may want to consider using one of our controllers equipped with a UXP Expansion Port. UXP is a standardized data port, specifically for the purpose of speaking to various expansion modules. This Relay Controller is equipped with a UXP port, allowing you to take advantage of extended commands to speak to our growing line of I/O expansion modules.
