Low-Cost 1 Relay Control

Single RS232 Relay

Our single relay controllers are among the smallest, most versatile relay controller we offer.  In fact, we believe this series to be the smallest serial relay controller on the market with the highest current switching capabilities.  Features include no-click startup, 1 LED status light, and E3C compliance.  Relays can be controlled at 9600 baud and is compatible with ANY computer or microcontroller capable of delivering RS-232 data.  For more information please click on the links below.

Single Relay ZigBee Controller

We now offer a Single Relay ZigBee Relay!  Plug our ZigBee Modem into the USB Port of your computer.  The modem will mount as a COM port on your PC.  Open the COM port and start sending data to the modem.  The modem will forward your data to all ZigBee compliant devices within range (it is also possible to speak to a specific device when other controllers are in range).
