Excellent PLC
Product Introduction
The Allen-Bradley 1771-IXE Thermocouple/Millivolt Input Module is an analog input module developed for the PLC-5 based 1771 I/O platform by Allen-Bradley. It is designed to process low-level signals from thermocouples and millivolt devices used in industrial temperature and process monitoring applications.
The module provides 8 floating differential input channels that allow accurate acquisition of low-level signals while reducing electrical noise and interference. With an input voltage range of ±100 mV, the module is suitable for precise measurement tasks commonly required in temperature monitoring and sensitive industrial processes.
Installed in a standard 1771 I/O chassis, the 1771-IXE communicates with the PLC-5 processor using block transfer communication. Its reliable signal acquisition capability makes it widely used in process automation, temperature monitoring systems, and industrial equipment where accurate analog measurement is essential.
