Cuttler Hammer Diagram

[Roy Matson]

Hi,
I have a bunch of obsolete CH D120PM20 circuit cards to repair
I tried to find a diagram or block diagram on the web.
If anyone has a diagram or even something identifying the pins I would appreciate a copy.
Also if someone knows the typical problems that go wrong with these cards and doesn't mind sharing likewise.

Thanks

Roy

C'mon guys, someone must know something about these cards.
