Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1746-NT4 is an Allen-Bradley Bulletin 1746 SLC 500 platform thermocouple/millivolt analog input module. It installs in a standard SLC 500 chassis (not in Slot 0) and provides four isolated input channels for temperature sensors or low-level voltage signals. It performs autocorrection of analog readings and offers selectable data formats; typical applications include industrial temperature monitoring, process control, and data acquisition in legacy SLC 500 systems. The part number is 1746-NT4.
