10 Module Overview
General Description The module stores digitally-converted thermocouple and/or millivolt
(mV) analog data in 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 and/or mV analog
sensors.
Input Ranges
The following tables define thermocouple types and associated
temperature ranges and the millivolt analog-input signal ranges that
each of the module’s input channel supports.
Refer to the specifications in Appendix A to determine the practical
temperature range of your thermocouple.
Each input channel is individually configurable for a specific input
device, and provides open-circuit, over-range, and under-range
detection and indication.
