Thermocouple modules (sometimes known as low level analog input
modules) provide six individually isolated differential inputs for
thermocouples or 10mV inputs plus one cold junction compensation
(CJC) input for temperature compensation at the terminal block.

The Isolated Thermocouple Module includes a jumper (W2) to
enable/disable LEDs on the module. Normally, you should keep the
LEDs enabled, but if power conservation is an issue, you could disable
the LEDs.
Description
Pins 1-2 installed = Enable LEDs (Factory default).
Pins 2-3 installed = Disable LEDs
