Product Applications
Mounting and Installation
Features:
- 1-channel isolated barrier
- 24 V DC supply (Power Rail)
- Dry contact or NAMUR inputs
- Passive transistor output, non-polarized
- Passive fault output, non-polarized
- Line fault detection (LFD)
- Reversible mode of operation
- Up to SIL 2 (SC 3) acc. to IEC/EN 61508
This isolated barrier is used for intrinsic safety applications.The device transfers digital signals (NAMUR sensors or drycontacts) from a hazardous area to a safe area.The input controls two passive transistor outputs.Via switches the mode of operation can be reversed and theline fault detection can be switched off.Via switch the function of the second output can be defined asa signal output or a fault indication output.A fault is signalized by LEDs acc. to NAMUR NE44 and aseparate collective error message output..
The KFD2-SOT3-Ex1.LB Pepperl+Fuchs Switching Amplifier may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The Pepperl+Fuchs KFD2-SOT3-Ex1.LB is a high-performance switch amplifier designed for transmitting digital signals from hazardous areas to safe environments. Below are the key technical notes regarding its configuration, wiring, and safety performance.Reverses the output logic. In "Normal" mode, the transistor is energized when the input is closed; in "Reversed" mode, it is energized when the input is open.Defines whether Output II acts as a Signal Splitter (mirroring Output I) or as a dedicated Fault Indication Output.Enables or disables monitoring for lead breakage and short circuits in the field wiring.
- Pumps & Turbines:Monitors shaft speed & status with NAMUR sensors
- Valve Positioners & Actuators:Tracks open/closed states & limits for chemical/oil pipelines
- Vessels & Tank Farms:Limit detection & overfill prevention for pharma/chemical tanks
- Conveyor Systems:Monitors speed, position & belt alignment in combustible dust environments
- Elevators & Hoists:Detects end-of-stroke & platform position in hazardous factory zones
- Heavy Mobile Machinery:Functional safety for forestry, mining & agriculture without ignition risk
