Selecting the Proper Amperage

To ensure you choose a board with the correct relay amperage for your load requirements, refer to Choosing a Proper Amperage.

Looking for a reliable wireless relay? These ProXR controllers offer wireless relay control for switching lights, motors, and devices with the XBee-PRO 900HP module.

Simple Wireless Communication

Boards on this page are equipped with a Digi XBee-PRO 900HP RF module that adds 900 MHz wireless communication to the controller. A USB modem connected to your computer sends commands wirelessly to the board. These controllers use Digi XBee-PRO 900HP mesh networking module to move data between devices when direct point-to-point communication is not possible.

The modem appears as a standard COM port on your PC. Simply send your commands to the COM port, and the modem forwards them wirelessly to the relay board. That's all there is to it!

900MHz Wireless Modem (required for PC-to-radio use)

Long Range Wireless RelayNot required when integrating into an existing XBee-PRO 900HP mesh network. Plug the UXSCMSR_ZIGMO (long-range) modem into the USB port of your computer. The modem installs as a virtual COM port, allowing your software to send data exactly the same way as a USB controller.

The modem can broadcast commands to all Wireless XSC-compliant devices within range, and can also be configured to communicate with a specific controller when multiple devices are present.

The modem is available at checkout.

💡 Relay Pros Pro Tip:

If you're controlling high-current loads such as motors or heaters, always choose a relay with extra amperage headroom. Operating a relay at its maximum rating can shorten its lifespan.
