USB Virtual COM Relay Controller with 8-Channels of
Analog to Digital Conversion and
XR Expansion Port
Our New USB ProXR Series Relay Controllers make it easier than ever to add computer controlled switching to your most demanding computer control applications. Simply connect to your computer and this controller mounts as a Virtual COM Port on your PC, allowing easy programming from any language that supports serial communications.
This ProXR series controller connects to the USB port of your computer and requires a 12VDC Power Supply. 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.

NOTICE: This Device CANNOT be used in inductive control applications. Click Here for More InformationWith all the control and backward/forward compatibility you have come to expect from the ProXR series command set, this controller allow you to send simple commands to activate relays, read the status of relays, activate up to 16 relay timers, and control up to 256 total relays using the XR Expansion Port. All relays are electronically latched, simply send a command to turn the relay on, send a different command to turn the relay off.
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. That's just the beginning, find out more about our ProXR Command Set.

Analog to Digital Conversion allows you to read voltage levels from 0-5 volts using 8-bit or 10-bit resolution. This is particularly useful for reading temperature sensors (one temperature sensor is built into the board, shared with analog input number 8). A/D Inputs are also useful for reading light level sensors, thermocouples, switch closures, or just about any other kind of sensor you can think of. Built-In Pull-Up/Down Resistors keep the inputs quiet. Eight Different A/D Sample programs are available in the NCD Component Library. These samples are available as a free download and are compatible with Visual Studio. We've got sensors! Visit our Sensor Page for sensors that have been tested and work with all NCD A/D Boards controller.

N-Button creates widgets or buttons to control up to eight relays without any programming. A new button will be created and placed on the desktop of your computer for each relay that you want to control. N-Button supports Serial Port/ USB and Network connection between PC and relay board. N-Button Manager makes it easy to add any type of button to the desktop and change the properties.
Analog to Digital meters can also be added to your desktop to instantly read the status of any sensor or probe you may have connected to the board. Each meter is customizable and can be changed without any programming knowledge.| Relay Button widgets turn on/off relay directly. It has never been so easy to control relays before. | |||
