Product Overview
The 1771-NT1 is an isolated analog input module for the Allen-Bradley PLC-5 / 1771 system. It provides eight input channels supporting millivolt and thermocouple signals, with per-channel scaling, alarm functions, rate alarm, and digital filtering. The module mounts in a 1771 I/O chassis and draws power from the backplane. It is typically used in industrial temperature or low-level voltage measurement applications requiring integration of thermocouple or millivolt signals into a PLC-5 control system. 1771-NT1 is now discontinued.
