The Allen-Bradley 1771-IFE is an advanced analog input module designed for the legacy PLC 5 Programmable Logic Controller line, providing versatile connectivity with either sixteen single-ended or eight differential inputs. Capable of handling voltage ranges from -10 to 10 Volts DC and current from -20 to 20 mA, this module efficiently converts analog signals into a 16-bit resolution digital format, ensuring accurate data representation for various process measurements such as temperature, pressure, and flow. Its robust design features automatic fault response, optoelectrical isolation for transient protection, and input filtering to mitigate electrical noise, making it an ideal choice for demanding industrial environments.
