ProXR Enhanced with A/D:
Not Just a Relay Controller Anymore!
It is one thing to build a relay controller with a powerful command set and lots of features. We have been doing that for years. It becomes an entirely different breed of controller when the relay controller is capable of watching over your computer when things don't always go as planned.
About the ProXR Standard
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.
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.
The features list of the ProXR series controllers is extensive. Our ProXR Software helps get you acquainted with the powerful command set. Should you have any questions, please

A/D Conversion
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.
