The Allen-Bradley 1771-IF05 is a Series B analog input module designed for the PLC 5 series, ideal for applications such as temperature, pressure, flow, and level sensing. It features 8 single-ended inputs supporting versatile voltage ranges from -10 to 10 Volts DC and current inputs of 4 to 20 milliamps, with a quick channel update time of 8 milliseconds in a resolution of 12 bits plus sign. Enhanced with optoelectrical isolation and input filtering for protection against electrical noise, the module also includes diagnostics through red and green LEDs for FAULT and RUN status and integrates seamlessly with the PLC system using a 1771-WB wiring arm, requiring only one slot in an I/O chassis.
