Product Description P/N: KFA5-SOT2-Ex2
Description
The Pepperl+Fuchs KFA5-SOT2-Ex2 is a two-channel switch amplifier and intrinsically safe isolated barrier designed to transfer digital signals from NAMUR sensors or mechanical contacts in hazardous areas to safe-area control equipment. It operates from a nominal 115 V AC supply and provides passive, non-polarized transistor outputs for compatible control circuits. Built-in line-fault detection and reversible output logic support reliable signal monitoring in industrial automation systems.

Information About KFA5-SOT2-Ex2
The KFA5-SOT2-Ex2 belongs to the Pepperl+Fuchs K-System interface module range and is designed for intrinsically safe digital signal transmission. Its two input channels accept NAMUR proximity sensors or dry-contact signals, with separate transistor outputs for the corresponding control channels. DIP switches allow the output logic to be reversed and line-fault detection to be enabled or disabled. The module supports applications involving hazardous-area equipment and carries a SIL 2 safety rating, subject to the requirements and conditions specified in the manufacturer's safety documentation.
Key Features:
-
Two-Channel Operation: Processes two independent digital input signals.
-
Intrinsic Safety: Provides an isolated interface for compatible hazardous-area sensor circuits.
-
NAMUR Input Compatibility: Accepts signals from NAMUR sensors and suitable mechanical contacts.
-
115 V AC Supply: Designed for a nominal 115 V AC supply.
-
Passive Transistor Outputs: Provides two non-polarized electronic outputs for control-side circuits.
-
Line-Fault Detection: Detects input-circuit wire breaks and short circuits when enabled.
-
Reversible Output Logic: Allows the operating mode of each channel to be configured using DIP switches.
-
SIL 2 Capability: Specified for safety-related applications within the manufacturer's stated conditions.
The KFA5-SOT2-Ex2 delivers the signal conditioning and intrinsic-safety interface required for compatible industrial automation and hazardous-area monitoring systems.
