both are used in a circuit analog end that get connected to temperate  sensors ( PT100 and KT40 )

Also this is part of a  Industrial compresser Slight smile

and the controlelrs says  it does not detedt the temp sensors and preshure  sensors  ( all controled by this part of the circuit )

some guy try to repaire this and messed every thing up Stuck out tongue
