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. The USB to Serial Adapter is to be used with the Quick Start Kit and is available at checkout.
Solid State a Practical Alternative to Mechanical Relays
Mechanical Relays have a good home in low-cost control applications. But for some users, only solid state switching will do. Solid State Relays are ideal for users who require long term reliability, silent operation, or high induction tolerance. Many inductive control applications require a solid state relay. Inductive loads such as Motors, Valves, Pumps, Solenoids, and Large Transformers (including Fluorescent Lighting) benefit from the use of solid state relays because they reduce the chances of the inductive load interfering with the logic of the relay controller.
You can purchase this controller with the relays installed two ways. You can have your choice of the same solid state relay installed in this board or you can choose different relays to be installed in each relay location. Simply choose the controller with _MIX in the part number and you will be able to choose specific relays for each location. If this controller is not a _MIX you can find it listed under Related Products on the right side of this page.
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.
NCD Component Library
Fully functioning programs for the ProXR Series Controllers are included with the NCD Component Library. With the NCD Component Library we've "started" the programming for you. We say started because these are fully functioning samples but we've also included the source code so you can customize them to your exact needs. 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 fully customizable to your needs. Many different ProXR Series samples are available including Relay Control, Read Status, Analog to Digital Conversion, Motion Detection, and Timing Features to view screen shots of each sample visit our
NCD Component Library Page.. Start by downloading the FREE NCD Component Library and you will be communicating with any NCD device faster that ever!
This sample demonstrates control and status read of up to 8 Relays.
Compatible with all ProXR Series Relay Controllers. |

Desktop Relay Control
N-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.
