FMR 204/12 4 CHANNEL RECEIVER WITH RELAYS

The FMR204-12 is a crystal controlled four-channel receivers, comprising of receiving, decoding and relay-output sections. A specially designed microprocessor is employed in the decoder section, which ensures operation at low supply voltage, highest reliability, associated with very low power drain.

The receiver works on a digitally encoded 27 MHz frequency modulated (FM) signal. It may be used in applications such as the remote control of garage doors, gates, lights, alarms or in any other new or existing installations where the use of conventional wiring is difficult or impossible to accomplish.

If the code of the input signal (from a transmitter) matches the setting of the 10-way code switch on the receiver (up to 1024 combinations), an output is obtained i.e. the relay operates. This relay provides a clean set of contacts for switching DC current up to 5 Amps. Code switches eleven and twelve are addressed by the four channels. The four channels are binary encoded on eleven and twelve.

The supply and antenna connections to the receiver are via a four-way screw-type terminal block, with a separate twelve-way terminal block for the relay connections.
