Carrier 32SM to 32MP

Does anybody remember when doing the conversion from the old style SM to the MP (still old style) on the motor winding sensors there is a module that has a transformer on it? I'm needing to refresh my memory here. Seems they used the original motor winding temp sensors and kept the little relay/transformer combo deal and used that as a digital to the I/O board? Can't seem to find a part# for that beaut in epic. Help, hints, reminders?

Thanks, Mike

I figured this out... The replacement is a Robertshaw Gard-pak module. Part number changed, imagine that. Of course it's to be expected when working on 30+ year old stuff!
