Check side label on controller for supply voltage before wiring.
Your choice of thermocouple types J, K, T, E, R, S, N, B,
J DIN, and the Pt100 2-wire RTD inputs are selectable via the keys
on the CN91XXA version of the controller. The CN92XXA controller
is configured to accept a 3-wire RTD input only. Figure 2-4 shows
how to wire any of these sensor inputs to the controller.
