USB Relay

USB Relay connects to a PC using a simple USB cable from your computer to trigger one or more relays on a circuit board.  Control one or more relays by sending commands to the board via the USB connection that will mount as a Virtual COM Port on a PC.  USB Relays offer excellent communication, speed and reliability through any available COM port at any standard baud rate.

USB Relay Options

USB Relays are available with SPDT 5, 10 and 20 amp, SPST 30 amp and DPDT 1, 3 & 5 amp relays installed.  In ProXR and ProXR Lite Versions.
