Front/rear light control interface circuit

for

c95 series decoder and MAXI loco with LED head/tail lights

Because of difference of circuit system between MAXI and standard gauge 1 locos, the c95 series (#6095, #60952, #60955) decoders cannot directly control head/tail lights of MAXI loco (example E10/E40).

Circuit diagram:

This diagram shows 'Lf=off / Lr=off' status.

How does it works?

This diagram shows 'Lf=on' status.

 

This diagram shows 'Lr=on' status.

 

This diagram shows 'Lf=on / Lr=on' status.

• This status never occur in normal operation.
• Series relay contact protects LED and output transistor of decoder from damage by short circuit.
