This is a receiver for switching turnouts, signals, and uncoupler tracks. The m 83 supports the digital formats Motorola, DCC, and mfx. The digital address can be set by means of coding switches or by means of the programming track in 4 steps. The address range in the Motorola format is up to 320 and in the DCC format up to 2040. The m 83 has 8 outputs that can be controlled separately or in pairs. These outputs are preset for switching up to 4 turnouts. Examples of other functions are switching up to 8 lighting circuits (dimmable) with a defined power-on behavior (example: street lighting, house lighting). External power supply is possible, example: by means of 66360/66365/66367, only in conjunction with 60822. The m 83 and m 84 decoders can be arranged in any sequence. A 60821 accessory set is required per pair of outputs for motor drives. Connections on the decoders are done by means of set-screw terminal clips. The maximum current load is 3 amps.
