Information About KFU8-SR-EX2.W
The KFU8-SR-EX2.W is a K-System switch amplifier from Pepperl+Fuchs designed for intrinsically safe signal transmission. It supports two input channels and accepts NAMUR proximity sensors or mechanical dry contacts. The module provides relay outputs with reversible switching logic and line fault detection for open-circuit and short-circuit conditions. It supports both 19–30 V DC and 90–253 V AC supply voltages and offers SIL 2 functional safety capability.
-
Two-Channel Design: Processes two digital input channels within one module.
-
Intrinsically Safe Interface: Transfers signals from compatible hazardous-area devices.
-
Input Compatibility: Accepts NAMUR sensors and dry-contact switches.
-
Relay Outputs: Provides changeover relay contacts for control-side switching.
-
Line Fault Detection: Detects open circuits and short circuits on the field input.
-
Reversible Logic: Allows the normal output switching state to be changed using DIP switches.
-
Universal Power Supply: Supports specified AC and DC supply ranges.
-
Functional Safety: Rated up to SIL 2 with systematic capability SC 3.
The KFU8-SR-EX2.W delivers the reliability and precision required for hazardous-area signal conditioning, process monitoring, and industrial control systems.
