Loco modules DCC

The image shows the CTC-Loco-Module-M3-DCC on the left and the CTC-Loco-Module-S3-DCC on the right.

The DCC variants of the CTC-Loco-Modules are optimized for controlling a DCC decoder. This allows you to keep the original DCC decoder in the locomotive and continue using original sounds with CTC.

The electrical properties are identical to the CTC-Loco-Module-M3 or CTC-Loco-Module-S3 . For the DCC signal, the motor output of the CTC-Loco-Module is used, meaning both have a DCC output power of 3.5 A peak (approx. 1.2 A continuous current).

Connection

To install, the track connection of the existing DCC decoder is disconnected and the track is connected to the CTC-Loco-Module-DCC. The motor output of the CTC-Loco-Module-DCC is connected to the track input of the DCC decoder:

Loco modules DCC

The IR receiver and capacitor are connected to the CTC-Loco-Module as usual.

IR Receiver

For each IR receiver, we provide you with a cable with a suitable 6-pin plug.

Buffer Capacitor

The cables for the buffer capacitor are already soldered to the CTC-Loco-Module:

  • The positive pole (VBB) goes to the orange cable.
    • The negative pole (GND) goes to the black cable.

Optionally, we can supply the CTC-Loco-Module-DCC already with a pre-soldered capacitor.

Pin Assignment and Dimensions

Details on pin assignment and dimensions can be found in the data sheets for CTC-Loco-Module-M3 or CTC-Loco-Module-S3 .
