3.1.2 Analog Inputs (AI)
Number of Devices: 12
Device Types: Analog Input, (4 to 20) mA or (0 to 5) V, 10 bit hardware.
There is one screw terminal connector for each analog input.
Terminals 18 to 29 are AI terminals.

3.1.3 Thermocouple Inputs (TC)
Number of Devices: 8
Device Types: Thermocouple Input, Type J or K, 12 bit hardware.
Open Thermocouple Detection: Drives terminal reading high (max of scale).
Automatic Cold Junction Compensation is
There are two screw terminal connectors for each thermocouple.
Terminals 1 to 16 are TC terminals 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 17, 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.
