Our Wireless Relays

Not to be confused with single function low-cost solutions, our Key Fob Reactor Relay Controllers are years ahead!  You can now send the same commands to the board as our computer controlled relays with a key fob you hold in your hand!  Use a button to activate a Relay, use another button to deactivate a relay.  Use another button to toggle a relay.  Use another button as a momentary switch.  Key Fob Controllers allow you to configure your Key Fob Buttons using the same command set as our computer controlled relays.

Our Remote Control Key Fob Relay boards offer your choice of 5, 10, 20 or 30 amp relays and are available with Solid-State AC or DC relays.  Key Fob relay boards operate at 12VDC with a on-board 2.1mm Barrel Connector or directly wire your own 12V power supply to the on-board screw terminals.
