General Description

The thermocouple/mV module receives and stores digitally converted

thermocouple and/or millivolt (mV) analog data into its image table

for retrieval by all fixed and modular SLC 500 processors. The module

supports connections from any combination of up to four

thermocouple or mV analog sensors.

The following tables define thermocouple types and their associated

full scale temperature ranges and also list the millivolt analog input

signal ranges that each 1746-NT4 channel will support. To determine

the practical temperature range your thermocouple supports, refer to

the specifications in Appendix A.
