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:

thermocouples, wire two in parallel to two modules. Use the same

channel on each module to make sure of consistent temperature

readings.
