Module Overview
This chapter describes the 1769sc-IT6I and the conformally coated 1769sc-IT6IK
Isolated Thermocouple/mV input modules and explain how the modules read
thermocouple or millivolt analog input data. Other than the conformal coating,
both modules are identical so all information applicable to the 1769sc-IT6I also
applies to the K version. The following section covers:
• The module's hardware and diagnostic features
• An overview of system and module operation
• Compatibility
The isolated thermocouple/mV input module supports thermocouple and
millivolt signal measurement. It digitally converts and stores thermocouple
and/or millivolt analog data from any combination of up to six thermocouple or
millivolt analog sensors. Each input channel is individually configurable via
software for a specific input device, data format and filter frequency, and
provides open-circuit, over-range and under-range detection and indication.

1.1.1 Thermocouple/mV Inputs and Ranges

The table below defines thermocouple types and their associated full-scale
temperature ranges. The second table lists the millivolt analog input signal
ranges that each channel will support. To determine the practical temperature
range your thermocouple supports, see the specifications in Appendix A.
