MiniTrix T66857 Locomotive decoder

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 interface. Universal use in Selectrix 1, Selectrix 2, and DCC format. Automatic analog detection and load control. Connection for light function and additional functions (Aux1 and Aux2). Short circuit fuse for the motor output. Extended Selectrix 1 programming of additional settings via selection of address "00", such as fine gradation of pulse widths (control variant) and direction of travel polarity. In Selectrix operation: 31 speed steps and 111 addresses. DCC operation: speed step selection of 14/28/126 speed steps. Addresses selectable short to 127 and long to 10239. Brake operation in DCC and SX format: DC same-pole/opposite-pole, brake diodes, asymmetrical 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, overtemperature, and short circuit. Newly developed motor control for extremely smooth operation of all common DC motors. Continued operation at the same speed after power interruption of up to 1 second. SUSI-controlled start-up delay (SUSI-WAIT). One- or two-part braking sections. Special features in analog operation include very low adjustable starting voltage, Vmax limitation, dynamic traction voltage-dependent dimming of light and AUX, programmable functions, and typical analog running behavior.
