SKU: 1771-IFE

Allen-Bradley 1771-IFE Analog Input Module

Enhance your PLC-5 system with the Allen-Bradley 1771-IFE. This 16-channel analog input module provides high-precision signal conversion, optical isolation, and support for voltage/current inputs.

Precision Analog Signal Conversion

The Allen-Bradley 1771-IFE drives high-resolution data acquisition for legacy PLC-5 control systems. This module converts diverse analog signals from field sensors into digital values that the processor can interpret. It supports 16 single-ended or 8 differential inputs, allowing you to interface with a wide variety of instruments measuring temperature, flow, and pressure. By utilizing 12-bit plus sign resolution, the 1771-IFE delivers the precision required for tight process control and accurate data logging.

Robust Signal Integrity and Filtering

Rockwell Automation engineered the 1771-IFE to excel in electrically noisy industrial environments. Optically isolated circuits protect the internal logic from external voltage surges, while programmable digital filtering smooths out signal fluctuations caused by EMI or RFI. These features ensure that the module provides a stable, clean data stream to the PLC-5 processor. Furthermore, the module executes high-speed block transfers to communicate with the CPU, ensuring your data tables reflect real-time field conditions with minimal latency.

Streamlined Maintenance and Safety

The 1771-IFE utilizes the 1771-WG wiring arm, which allows you to replace the module without disturbing any field wiring. This “swing-arm” design slashes downtime during maintenance cycles. To prevent hardware damage, integrated keying bands ensure that you only insert the module into correctly configured chassis slots. Front-panel LED indicators provide immediate visual feedback on the module’s status, helping technicians quickly distinguish between normal “RUN” operations and “FAULT” conditions.
