PLCAGE: 1746-NR4 Allen-Bradley PLC 1746 RTD and Thermocouple Modules 4 Input 16 bits New

Features

The RTD module receives and stores digitally converted analog data from RTDs or

other resistance inputs such as potentiometers into its image table for retrieval by

all fixed and modular SLC 500 processors. An RTD consists of a temperature-sensing element connected by 2, 3 or 4 wires that provide input to the RTD module.
