Please use shielded wires to acquire best noise immunity. If you use shielded wires, connect the shield to the ground on pin 1 to 4 of the signal connector. This ground is the same ground as is present on the power connector pin 3 to 7. If you do not use an RTD input channel, you should wire a resistor to the unused channel inputs in order to prevent errors from floating inputs from blocking error indications from valid channels.
Connect user power to the power connector pin 1 and 2. You must connect pin 3 to a nearby chassis ground (Figure 2).
You can wire the RTD module to the sensor in three ways (shown in Figure 3). The most accurate mode is 4 wire (see Figure 3). The least accurate mode is 2 wire, which is only recommended if errors due to wiring can be ignored in your application.

Configuration
The EM231 RTD modules provide a convenient interface to connect CTS7-200 PLC to several different RTDs. It also allows the CTS7-200 PLC to measure three different resistance ranges. You must use DIP switches to select RTD type, wiring configuration, temperature scale, and burnout direction. Both RTDs connect to a module must be of the same type.
The configuration DIP switches are located on the right bottom of the module, as shown in Figure 4. For the DIP switch settings to take effect, you need to power cycle the PLC or the 24V power supply.
Selecting the RTD type
Select RTD type by setting DIP switch 1 to switch 8 to correspond to the RTD as shown in Table 1 and Table 2.
