Product Description
Overview
The Allen-Bradley 1771-IFE is a high-performance analog input module designed for the PLC-5 platform within the 1771 I/O system. It provides reliable acquisition of voltage and current signals in demanding industrial control systems.
This module supports both differential and single-ended configurations, making it suitable for diverse process instrumentation applications. Engineers commonly deploy the 1771-IFE in legacy PLC-5 systems for temperature, pressure, flow, and level monitoring.
It installs directly into any 1771 I/O chassis and communicates with the PLC-5 processor via the backplane. No external power supply is required.
