Product Description
PEPPERL+FUCHS Safety Barrier Switch Amplifier KFD2-ST3-Ex1.LB
The PEPPERL+FUCHS KFD2-ST3-Ex1.LB is a 1-channel isolated barrier designed for intrinsic safety applications in hazardous areas. This safety-rated device provides reliable signal transmission from hazardous zones to safe areas while maintaining SIL 2 (SC 3) compliance according to IEC/EN 61508 standards.
Key Features
- 1-channel isolated barrier for intrinsic safety applications
- 24 V DC power supply via Power Rail
- Accepts dry contact or NAMUR sensor inputs
- Dual active transistor outputs
- Configurable as signal splitter (1 input, 2 outputs)
- Reversible mode of operation
- Line fault detection (LFD) capability
- SIL 2 (SC 3) safety rating per IEC/EN 61508
Functional Operation
This isolated barrier transfers digital signals from NAMUR sensors or dry contacts located in hazardous areas to safe area control systems. The input signal controls two independent active transistor outputs. Device configuration switches allow for operation mode reversal, line fault detection enable/disable, and output function selection (signal output or error output). Fault conditions are clearly indicated via LEDs following NAMUR NE44 standards, with a dedicated collective error message output for system integration.
