Receiver for all DC locomotives with a total current consumption of up to 1000 mA (motor 1000 mA, 200 mA per light). Suitable for digital locomotives with an mtc14 digital connection. Universal use in Selectrix 1, Selectrix 2, and DCC formats. Automatic analog detection and load regulation. Connection for light function and additional functions (Aux1 and Aux2). Short-circuit protection for the motor output. Advanced Selectrix 1 programming of additional settings via the address selection "00", such as fine adjustment of pulse widths (control variant) and direction polarity. In Selectrix operation: 31 speed steps and 111 addresses. DCC operation: selection of speed steps from 14/28/126 speed steps. Addresses selectable short up to 127 and long up to 10239. Brake operation in DCC and SX format: DC same polarity/alternating polarity, brake diodes, asymmetric track signal, and brake generators. Dimensions approximately 14 x 9 x 2 mm.

Robust multiprotocol retrofit decoder, short-circuit proof between motor and track. Safety shutdown in case of overcurrent, overheating, and short circuit. Newly developed motor control for extremely smooth operation of all common DC motors. Continuous operation at the same speed after a power interruption of up to 1 second. SUSI-controlled start delay (SUSI-WAIT). Single or double-segment braking sections. Special features in analog operation include very low adjustable starting voltage, Vmax limitation, dynamic, traction-dependent dimming of light and AUX, programmable functions, and typical analog driving behavior.
