10 channel high security (rolling-code) UHF remote control relay board for use in a variety of applications. One receiver board can be used with up to 15 transmitter key fobs making it ideal for a multi-user access or control system.

Whether you want to control a garage door or gate, a car and/or home alarm, or perhaps remotely turn lights or anything else on or off, this system is just what you're looking for!

  • Rolling-code security (as used for vehicle security systems) is almost impossible to electronically crack
  • Each of the ten channels can be set to either LATCHING (Toggle) or MOMENTARY operation so it's extremely versatile*
  • Long 40 metre range (line of sight)
  • The key fob transmitter and UHF receiver module are both pre-built
  • Up-to 15 key fob transmitters (Tx) can be used with one receiver board (one key fob transmitter is included as standard)

The Technical Documentation describes how key press combinations give readable outputs: pins 1, 2, 3, and 4 (of course) and the pins 1&2, 1&3, 1&4, 2&3, 2&4, and 3&4 pressed together. A pre-programmed PIC micro-controller handles the logic (source code is provided for educational purposes).

*The Receiver board defaults to Momentary Mode for all relays but can be changed to Toggle Mode by holding the button or keypress combination depressed for more than 2 seconds. That relay will stay in that mode until another >2 sec keypress is received (NB a firmware upgrade is available that changes this arrangement - see our Firmware Chips page for details). Small relays are used to save weight and board area.

The kit is supplied with all the components to build one complete 10 channel relay board (as pictured). One ready built 4-button keyring transmitter (with battery) is also supplied but up to 15 transmitter units can be learnt by one Rx unit. Extra transmitter units can be purchased separately (Order Code 30A16-Tx).
