TEMPERATURE INPUTS
There are four distinct temperature inputs available: Bath, Outlet, Stack, and Aux. The Bath, Outlet, and Stack
inputs are configurable to accept either a Type-K thermocouple or a PT-100 RTD sensor. The Aux temperature
input on terminals 43-44 is intended to be connected to a temperature sensor with a 4-20mA interface.
The Bath input is mandatory and must be connected to a Dual Element temperature sensor. The Outlet, Stack,
and Auxiliary temperature inputs are optional and can be utilized to monitor secondary process temperatures
such as the outlet temperature on a line heater. Unused temperature input terminals can be left unconnected.
When wiring thermocouples, Type-K thermocouple extension wire must be utilized to avoid cold junctions,
leading to inaccurate readings.
Below are the wiring diagrams for the Type – K Thermocouple and the RTD Temperature inputs.
