Allen-Bradley 1771-IFC Analog Input Module
The Allen-Bradley 1771-IFC is an analog input module designed for the PLC-5 control platform. It provides signal acquisition for process control applications by interfacing up to 8 single-ended analog input channels with the system backplane. Converting incoming analog signals into 12-bit digital values, it enables precise monitoring of field instruments, process sensors, and industrial equipment.
Signal Processing and System Architecture
Each of the 8 single-ended input channels can be configured to process either voltage or current signals from standard process loops and transmitters. The module performs 12-bit analog-to-digital conversion, delivering high-resolution digital representations of measured process variables directly to the PLC-5 processor for control logic execution, data logging, and alarm evaluation.
Mechanical and Installation Specifications
Designed for direct installation into a standard 1771 I/O chassis, the module connects via the 1771 backplane for power and communication. Weighing approximately 1.70 lbs (0.77 kg), it fits into a single I/O slot, maintaining compatiblity with legacy Allen-Bradley PLC-5 rack architectures.
