For installation in locomotives that do not already have a suitable plug or socket, we have created an adapter with a PluX22 interface.
| Property | Description |
|---|---|
| Optimized for | Locomotives without digital interface |
| Dimensions | 30 x 14.5 mm |
| Interfaces | PluX22 socket, optional SUSI socket |
We deliver the adapter in three variants (from left to right):
- Only with PluX22 socket
- With PluX22 socket and SUSI socket
- With PluX22 socket, SUSI socket, and screw terminals
The circuit board also provides space for:
- 2 diodes for connection of motors with field coils (e.g., old Märklin locomotives).
- one diode each for front and rear lights for connection of lighting with only one wire (second pole on the housing).
Notes:
- For IR receivers and NFC readers, there are no suitable connections in the standard PluX22. Therefore, these are connected to the CTC locomotive module via the separate 10-pin socket.
- In the locomotive module PluX22, the headlight is configured as a switch against minus (LowSide). If it is to switch against the positive pole (HighSide), the light must be removed in the config dialog and replaced by one with HighSide. See the conversion of the Märklin BR53 (Borsig I). null## Wiring
The example shows the wiring of an old analog locomotive with field coil and electrical couplers at the front and rear:
Here is the view from the rear, as it results, for example, with the version with screw terminals:
The diodes must be ordered separately and soldered on by yourself. The PluX22 socket is always soldered on.
The hole in the circuit board is electrically connected to Track-1, so this connection can alternatively be made via screwing to the housing. In old Märklin locomotives, the circuit board can be screwed where the reverser was previously fixed. A cable to the wheels/housing is then not necessary.
If the locomotive has a permanent magnet, the two right diodes are omitted and the upper one is replaced by a piece of wire. The motor is then connected to Motor+ and Motor-A. Motor-B remains unoccupied.
If the front and rear lights have two wires (i.e., no connection to the locomotive housing), the two left diodes can be replaced with pieces of wire.
