The CTC-Loco-Module-PluX22 is sold out. The successor is the CTC-Loco-Module-M3 .

The CTC-Loco-Module-PluX22 is designed for locomotives with the standard PluX22 socket . Due to the standardized plug, this loco module can be installed without soldering. For older locomotives, various adapter boards with larger solder pads, cables or for NEM-652 (8-pin), NEM-651 (6-pin) are available on the market.

Pin assignment

Details on pin assignment and dimensions can be found in the RailCommunity Standard RCN-122 .

Loco module PluX22

Connection

Notes:

  • When selecting the input voltage, please remember that motors, lights, etc. connected to the CTC module must also be compatible with this voltage The AUX-7 connection is not used.
  • The train bus can be used as a SUSI interface.

To connect:

  • plug the CTC module onto the 22-pin PluX22 socket of the locomotive.
  • plug the optional CTC IR receiver onto the 10-pin socket on the CTC module (red marking points to the center of the board)

The assignment of light and AUX connections to switches in the app can be freely configured (Cfg.xml).

Further connections

  • An NFC reader can be connected to NFC-TX, NFC-RX, VCC and GND, e.g. for small H0 scale locomotives.
  • Two digital inputs are available at ExtIn-1 and ExtIn-2

IR receiver

We supply you with a cable with a suitable 10-pin plug for the IR receiver. Installed in a Piko locomotive BR 147 (#51583-2), it looks like this:

Note: Since the support capacitor was not wired in the Piko locomotive, we soldered it directly to our CTC-Loco-Module-PluX22.
