3.2.2 Thermocouple Inputs (TC)
Number of Devices: 8
Device Types: Thermocouple Input, Type J or K, 12 bit hardware
Open Thermocouple Detection: Drives channel reading high (max of scale).
There are two screw terminal connectors for each thermocouple input.
Terminals 109 to 124 are TC channels where White or Yellow indicate positive inputs and Red indicates negative inputs.
An additional terminal connector is provided, identified as SHD, which isolates thermocouple shields. This con- nection, at terminal 125, is intended to be wired to an isolated bus bar for thermocouple shield wires. If ground- ed thermocouples are used, the shied terminal should not be connected.
