Features	2-Channel Isolated Barrier, Line Fault Detection (LFD), Reversible Mode of Operation

The Pepperl + Fuchs KFD2-SOT-EX2 is a high-performance switch amplifier designed to facilitate the safe and efficient transfer of digital signals from hazardous areas to secure environments. This 2-channel isolated barrier is engineered to operate with a 24 V DC supply via Power Rail, ensuring compatibility with a wide range of industrial power systems.

Equipped with isolated dry contact or NAMUR inputs, the KFD2-SOT-EX2 offers flexibility for various application requirements, including those that necessitate line fault detection (LFD) for enhanced operational integrity. The device boasts isolated passive transistor outputs, which are meticulously designed to handle signals in the safe area load with utmost reliability.

The KFD2-SOT-EX2's inputs are intrinsically safe, and the outputs are isolated from each other, providing an additional layer of protection and system integrity. Users can easily reverse the normal output state using the accessible switches, allowing for customised operation to suit specific process needs.

Featuring a compact and robust design, the KFD2-SOT-EX2 is housed in a space-efficient enclosure that ensures a minimal footprint within control panels or system assemblies. Its removable terminals facilitate straightforward installation and maintenance, while the LED indicators provide clear and immediate status feedback, adhering to NAMUR NE44 recommendations.

This switch amplifier is an essential component for industries that require precise and secure signal transmission, making it an ideal choice for sectors such as chemical processing, oil and gas, pharmaceuticals, and other environments where safety and reliability are paramount.
