Each channel accepts voltage and resistance inputs. Resistance measurement by digital voltage drop
Generated at both ends of the input resistance source. The precision constant current source is used to measure the cold junction reference ASI module for measuring the cold junction RTD on the terminal unit of the analog input module. This leads to
Terminal area for accurate reading of ambient temperature at field wiring. This value can be used by ASI module to: compensate the voltage generated by bimetal Figure 2-1 IMASI23 Functional Block Diagram IG ITA L Multiplexer NVRAM Dual Port Memory

WBPEEUI240774A0 2-3 is connected to the terminal block of the terminal unit by terminating field wires (thermocouples). The block address of the cold junction reference used for thermocouple input on the ASI module is contained in FC 215, Specification S3. Each analog input module is configured with a thermocouple input that requires a cold junction reference. Each analog input module can only have one reference, which can be used for thermocouple input by up to 16 people. The exception is when the input is used as a remote cold contact reference. See Section 4 for more information.
