Product Description:
The Pepperl+Fuchs KFD2-SOT3-EX1.LB is a 1-channel isolated switch amplifier for intrinsic safety applications. The KFD2-SOT3-EX1.LB operates with a 24 V DC supply and supports a switching frequency of up to 5 kHz.This device functions as a signal conditioner, transferring digital signals (NAMUR sensors or dry contacts) from hazardous areas to safe areas.
What sets the KFD2-SOT3-EX1.LB apart is its reliable Line Fault Detection (LFD) capability, which monitors field circuits for lead breakages or short circuits. Featuring three transistor outputs (one signal output and two error outputs), it ensures maximum process transparency and safety for critical industrial systems.
Application:
Oil and gas: High and low liquid level switches in the oil tank area of the refinery, wellhead devices, valve opening/closing positions on the oil production platform.
Chemical and petrochemical: Pressure/liquid level interlock alarms for reaction vessels and storage tanks.
Pharmaceutical industry: Signal collection of equipment status in centrifuges and explosion-proof areas of clean rooms in pharmaceutical factories.
Food and feed processing: Material level monitoring in flour mills and grain warehouses under dust explosion environments.
Core Function:
Single-channel isolation barrier: Supports 24 V DC power supply (can be powered through rails).
Input port: Compatible with NAMUR sensors or dry contacts (passive contacts).
Output port: Features two passive transistor outputs (non-polarized), which are electrically isolated from each other.
Signal distribution function: The second output can be configured as a signal output (as a splitter) or a fault indication output based on the switch settings.
Safety certification: Compliant with SIL 2 (SC 3) standards, suitable for environments with requirements for functional safety.
