14 Module Overview
Module Addressing
The module requires eight words each in the SLC processor’s input
and output image tables. Addresses for the module in slot e are as
follows:
I:e.0…3 thermocouple/mV data for channels 0…3, respectively
I:e.4…7 status data for channels 0…3, respectively
O:e.0…3 configuration data for channels 0…3, respectively
O:e.4…7 reserved for future use. Do not use.
Compatibility with Thermocouple and Millivolt Devices and
Cables
The module is compatible with the following NBS MN-125 and -161
standard types of thermocouples: B, C, D, E, J, K, N, R, S, and T and
extension wire. The module is also compatible with a variety of mV
devices with an output of ±50 or ±100 mV.
Refer to Appendices A and C for details.
To minimize interference from radiated electrical noise, we
recommend twisted-pair and highly shielded cables.
