Description
Product Description
The Allen-Bradley 1771-IXE is an isolated analog input module designed for the PLC-5 and 1771 I/O platform. It is engineered for precision measurement of low-level analog signals, specifically thermocouple and millivolt inputs, in industrial process monitoring and temperature acquisition systems.
This module supports floating differential inputs with full channel isolation, enabling stable signal acquisition in electrically noisy environments. It can process up to eight input channels configured either as a single input type or split between two supported signal types. Communication with the PLC-5 processor is handled through block transfer, ensuring synchronized and reliable data exchange.
The 1771-IXE includes automatic calibration functions for offset and gain correction, improving measurement stability over time. It is compatible with all standard 1771 chassis and requires the 1771-WI wiring arm for field connection.
