This is a receiver for turning continuous current on and off for lighting, motors, Hobby signals (74371, 74380, 74391) and other electric accessories. The m 84 supports the Motorola and DCC digital formats. The digital address can be set using the coding switches or by means of a programming track. The available address range in the Motorola format is up to address 320 and in the DCC format up to address 2040. The m 84 has 4 relays for galvanic separated control of users. If you use the 66361/66365 switched mode power packs to power circuits connected to these relays, you can achieve bi-stable status for the relays and store in memory the last control activity. The Hobby color light signals can be controlled with the same control potential for the track current. In addition, the m 84 has 8 inputs for manual control of the relays (analogous to the 7244 remote relay). The 60831 and 60841 decoders can be arranged in any order desired. Connections are done with set screw terminals. The maximum current load is 5 amps.
