NASM01 | ABB Bailey Analog Input Module

The ASI module measures the cold junction RTDs on the termination unit of the analog input module. This results in an accurate reading of the ambient temperature at the field wire termination area. This value can be used by the ASI module to compensate for voltages generated from the bimetalEach analog input module can only have one reference which can be used by up to 16 thermocouple inputs. The exception to this is when one of the inputs is used as a remote cold junction reference.
