This is a receiver for switching turnouts, signals, and uncoupler tracks. The m83 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 m83 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 m83 and m84 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.
