Description
Product Overview
The Pepperl+Fuchs KFD2-SR2-Ex2.W belongs to the K-System family of isolated switch amplifiers. It transfers switching signals from suitable field devices to control-side equipment while providing electrical isolation between circuits.
The module supports two-channel operation and is designed for NAMUR sensors or dry-contact inputs. Line-fault detection can identify specified open-circuit and short-circuit conditions, helping control systems recognize certain wiring faults. The device is intended for industrial process automation and suitable hazardous-area interfaces when the complete installation meets the applicable requirements.
