The CTC-Locomotive Module-H0d is no longer offered. As a replacement, you can use the CTC-Locomotive Module-PluX22 with an installation adapter.
The CTC-Locomotive Module-H0d is optimized for installation in older locomotives that are either already digital or were offered as a digital variant. Locomotives with many functions benefit from the 10 switching outputs and 2 servo connections of this locomotive module. With an additional motor driver module, a second motor can also be controlled.

Pin Assignment
Connection
Standard configuration
- Connect the contacts Track-A and Track-B to the track or the power supply. Alternatively, Track-A can also be connected via a screw (hole in the board). It does not matter whether you supply the track with an analog transformer, a digital central unit, or a power supply, as long as the maximum voltage of 24 V is not exceeded. Since a rectifier hangs at the input, it also doesn’t matter which pole you connect to Track-A and Track-B.
- Connect the backup capacitor (electrolytic, min. 400 uF, recommended 1000 uF) to VBB (positive pole) and GND.
- Connect the motor with Motor + and Motor - (for connecting the electromagnet of universal motors, see separate instructions).
- Connect the negative poles of the front lights with SW-1 and the rear lights with SW-2. Connect the positive pole to any VBB connection.
- Optionally, connect other SW connections, e.g., with the negative pole of the electric coupling, the smoke generator, or other lighting. Connect the positive pole to any VBB connection.
- Connect the CTC IR receiver to the programming connector (RX, VCC, GND)
The assignment of pins to switches in the app can be freely configured (Cfg.xml).
Additional Connections
The I2C bus, servos, second motor, and reserved pins are not supported by the current firmware. Please contact us if needed.
