The CTC-Locomotive Module-H0a is sold out and will no longer be offered. As a replacement, you can use the CTC-Locomotive Module-PluX22 or CTC-Locomotive Module-21mtc with installation adapter.
The CTC-Locomotive Module-H0a is optimized for installation in old analog locomotives, in which one pole of the lighting is permanently connected to the housing. The four switch outputs are sufficient for front and rear lights and, e.g., two electric couplers or one electric coupler and one smoke generator.

Connection
Notes:
- When selecting the input voltage, always remember that motors, lamps, etc. connected to the CTC module must also withstand this voltage!
Standard Configuration
- Connect the 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 you supply the track with an analog transformer, a digital command station, or a power supply, as long as the maximum voltage of 24 V is not exceeded. Since a rectifier is connected at the input, it does not 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 to Motor + and Motor - (for connection of the electromagnet of universal motors, see separate instructions).
- Connect the positive pole of the front and rear lights to the respective terminals. Connect the negative pole to GND or via a diode to the negative of the track connection.
- Optionally connect Aux terminals to the positive pole, e.g., of the electric couplers. Connect the negative pole to GND or via a diode to the negative of the track connection.
- Connect the CTC IR receiver to the programming connector (RX, VCC, GND).
The assignment of the 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.
