The Allen-Bradley 1771-IFE is a versatile analog input module designed for seamless integration with the PLC5 series, providing exceptional flexibility with its choice of sixteen single-ended or eight differential inputs. This module offers a broad range of input signal selections, accommodating various voltage and current levels such as 1 to 5V DC, 4 to 20 mA, and -10 to 10V DC, ensuring compatibility with numerous industrial applications, including pressure, temperature, and flow measurement. With features like 16-bit resolution for precise analog-to-digital conversions, automatic fault response configuration, and BCD or Natural Binary scaling options, the 1771-IFE ensures reliable, predictable operation, while reducing electrical noise through digital filtering and optoelectrical isolation to protect circuits from transients. Furthermore, its efficient design incorporates real-time sampling and occupies only a single slot in a PLC5 chassis, making it a robust choice for various process automation environments.
