4. Connect the thermocouple wires Reference
Connect thermocouple wires to channel 0 on the module’s terminal block. Make sure both cold
junction compensation (CJC) assemblies are securely attached.
Ground the shield drain wire at one end only. The preferred location is to the same point as the
sensor ground reference. For grounded thermocouples or mV sensors, this is at the sensor. For
insulated/ungrounded thermocouples, this is at the NT4 module.

code (3510).
When using RSLogix 500 version 6.10 or higher, you may select Advanced Configuration, then
Configure, to use the software’s I/O wizard to configure the NT4 (see appendix E for details). If
you use this option, proceed to step 8.
