PLCAGE: 1746-NT4 Allen-Bradley PLC 1746 RTD and Thermocouple Modules 4 Input 16 Bits New

Features

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.
