FLEX I/O Modules 3-11
Wiring the Thermocouple Input Module
In addition to following the General Considerations when using Any FLEX
I/O Analog Input Module on page 3-7, before wiring the module, consider
the following application guideline:
• Wire to Same Input Channel on Both Modules: When wiring
thermocouples, wire two in parallel to two modules. Use the same
channel on each module to make sure of consistent temperature
readings.
