The CTC-Loco-Module-H0a is sold out and is no longer offered.
As a replacement, we recommend the CTC-Loco-Module-M3 with cables or with PluX22 and our CTC-Adapter for PluX22 .
The CTC-Loco-Module-H0a is optimized for installation in old analog locomotives where one pole of the lighting is permanently connected to the chassis.
The four switching outputs are sufficient for front and rear lights and, for example, two electric couplings or one electric coupling and a smoke generator.

Connection
Notes:
- When selecting the input voltage, please remember that motors, lamps, etc. connected to the CTC module must also be compatible with this voltage
Standard configuration
- Connect contacts Track-A and Track-B to the track or power supply. Alternatively, Track-A can also be connected via a screw (hole in the PCB). It does not matter whether the track is powered by an analog transformer, a digital control unit, or a power supply, as long as the maximum voltage of 24 V is not exceeded. Since there is a rectifier at the input, it does not matter which pole you connect to Track-A and Track-B.
- Connect the support capacitor (electrolytic, min. 400 µF, recommended 1000 µF) to VBB (positive pole) and GND.
- Connect the motor to Motor + and Motor - (for connecting the electromagnet of universal motors, see separate instructions).
- Connect the positive pole of front and rear lights to the corresponding terminals. Connect the negative pole to GND or via a diode to the negative pole of the track connection.
- Optionally, connect Aux terminals to the positive pole, e.g. of the electric coupling. Connect the negative pole to GND or via a diode to the negative pole of the track 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 and the other "Reserved" pins are not supported by the current firmware.
