Receiver to switch nominal current on and off for lights, motors, Hobby signals (74371, 74380, 74391) and other electrical accessories. The m 84 supports the digital formats Motorola, DCC and mfx. The digital address can be set via coding switch or via the programming rail in 4 steps. The address range is available in Motorola format up to address 320 and in DCC format up to address 2040. The m 84 contains 8 relays in 4 galvanically isolated groups for switching the consumption points. By using a power supply 66360, the bistable state of the relays and the storage of the switching state can be performed. 4 Hobby signals and 4 Hobby presignals can be controlled when the driving current is switched simultaneously. Furthermore, the m 84 counts 8 inputs for manual relay switching (as for the 7244 solenoid switch). The m 83 and m 84 decoders can be connected as desired. Connection is via elevator terminals. The maximum current carrying capacity per group is 5A.
