SLC 500 RTD/Resistance Input Module  four-channel

The RTD module receives and stores digitally converted analog data
from RTD units or other resistance inputs such as potentiometers into
its image table for retrieval by all fixed and modular SLC 500
processors.

An RTD module consists of a temperature-sensing element
connected by two, three, or four wires that provide input to the RTD
module. The module supports connections from any combination of
up to four RTD units of various types
