The Allen-Bradley 1771-IFEK is a Conformal-Coated PLC 5 Analog Input Module designed to withstand humidity and contaminants through its protective polymeric film. With its capability to handle up to 16 single-ended or 8 differential inputs, the module efficiently converts signals to a proportional 4-digit BCD or 12-bit binary value, offering various voltage and current input ranges, including 1 - 5V DC and 4 - 20mA. Notably, it integrates seamlessly into a 1771 I/O chassis without requiring an external power supply, features block transfer programming for effective data exchange, and provides both visual indication of operational status and advanced noise reduction through optoelectrical isolation and digital filtering.
