RTD Terminations
RTD wiring is connected to the screw terminals located at the
bottom of the termination panel as shown in Figure 16. When
terminating RTD wiring, follow the recommendations listed
below.
1. Greater accuracy is maintained with a heavier gauge RTD
lead wire. Lead wire resistance should not exceed
20 Ohms.
2. All RTDs within a group of eight must be the same RTD
type (American or European) and use the same number of
leads (2, 3 or 4-wire). 2-wire and 4-wire RTDs can be mixed
in the same group.
3. For unused RTD inputs, short the +SENSE, -SENSE, and
-FORCE terminals together.
