That the OC32/NG is a versatile accessory decoder was already known. But it is possible to control up to 64 magnetic coils with the 32 outputs. For this we use the Multiplex principle of the OC32 software and hardware.

By using 16 outputs you can connect up to 32 magnetic coils with 4 MDdec modules. The other 16 outputs remain available for other applications. Would you also connect a multiplex matrix with again 4 MDdec modules then you get the possibility to drive 64 magnet coils.

Below you can choose from 4 options:

OC32-MX/32T: for 32 magnetic coils with screw terminals 
OC32-MX/32P: for 32 magnetic coils with plug-in terminals 
OC32-MX/64T: for 64 magnetic coils with screw terminals 
OC32-MX/64P: for 64 magnetic coils with plug-in terminals 

Hint:
When using Dinamo and iTrain select "OC32X aspect" as output device for all addresses at each turnout
