ProXR - The Most Powerful Relay Control Available!
RS-232 ProXR Relay Controller
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.
Three RS-232 Connection OptionsThere are three RS-232 connection options available for this controller.
Wire It Up
Plug It In
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.
Built with Expandability in Mind
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.
Using XR and UXP Together
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.
About Universal Expansion Ports
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.
N-ButtonN-Button & N-Button Lite is software that allows you to configure buttons to control relays and read the status of those relays without programming. You can also create meters for reading variable input sensors connected to the board in real time! N-Button will allow you to create unlimited widgets and N-Button Lite will allow you to create up to 8 widgets.
When you create custom buttons in N-Button & N-Button Lite you can use any of the commands that are in a ProXR Command Set that is available with this relay. You can find the full command set here. It's quite extensive and you can configure the buttons to activated these commands. These buttons will be on your desktop of your computer and when you click on a button it will send the command to the board provided the board is connected to the computer. You can also change the shape, color and text of each button so you will know exactly what each button controls.
Relay Button widgets turn on/off relays directly. It has never been easier to control relays, no programming skills required. Create a button that turns a relay on and another one to turn the relay off or create a button that toggles the relay on and off. It's up to you and easy to configure with the N-Button Lite software!
Relay Status Relay Status widgets shows the status of the relay automatically. Just a glance at your desktop will show the status of the relay!
