Description
The FMR-24002 is a crystal controlled single channel receiver, comprising of receiving, decoding and relay-output sections. A specially designed micro-controller is used in the decoder section, which ensures operation for highest reliability.
The toroidal transformer on this receiver is 25-30% more efficient than the conventional types. It has a low operating temperature, low hum and low stray magnetic field.
Connection to the receiver is via an eight -way screw-type terminal block. An on board LED indicates when power is connected and an extra LED on the board to indicate when the relay is activated. There is a test button for the relay output to test your connections.
The receiver’s high capacity output relay is capable of switching up to 16 Amps of resistive load and up to 8 Amps of inductive load. A world first for a standalone receiver.
The receiver can be mounted to a Quick Mount or in a weatherproof case with an IP66 rating.
Elsema’s ANT27MHz series antennas will give a reliable control range of up to 200 metres, when used with Elsema’s FMT-301, FMT-302 and FMT-304 transmitters.
Different Modes for the Output
Modes are user selectable from the 2-way dipswitch. Dipswitch 1 corresponds to relay channel 1 and dipswitch 2 corresponds to relay channel 2.
| Momentary Mode |
If the dipswitch is “off” the relay will be in momentary mode. |
| Flipflop Mode |
If the dipswitch is “on” the relay will be in flipflop mode. |
| Latching |
If latching is required (Relay stays on until power is removed) the latching link should be inserted and soldered into the two holes to the right of the 2-way dipswitch. This will enable corresponding relays to latch. |
Care must be taken, not to bring a receiver near strong magnetic fields, such as DC-Motors, speakers, magnets for reed switches, transformers etc. as it would magnetise the coils and may cause severe de-tuning.
