The Pepperl + Fuchs KFD2-SOT2-EX2 Switch Amplifier is a robust and reliable solution designed to facilitate the transfer of digital signals from hazardous areas to safe zones. This 2-channel isolated barrier is engineered to work with both dry contact and NAMUR inputs, making it a versatile choice for a variety of industrial applications.

Equipped with a 24 V DC supply via Power Rail, this switch amplifier ensures a streamlined power connection while maintaining a high degree of safety and efficiency. The unit features isolated passive transistor outputs that are non-polarized, providing flexibility in connecting to the safe area load. Additionally, the outputs can be easily reversed using the onboard switches, allowing for customisable control based on specific operational requirements.

The KFD2-SOT2-EX2 also includes line fault detection (LFD) capabilities, which are essential for monitoring the integrity of the control circuit. This feature can be activated or deactivated as needed, offering additional control to the user. In the event of an error condition, the device's transistors revert to their de-energized state, and the fault is clearly indicated by the integrated LEDs in accordance with NAMUR NE44 standards.

Designed to accommodate up to SIL 2 according to IEC/EN 61508, the switch amplifier ensures a high level of functional safety, making it suitable for use in environments where safety is paramount. Its compact dimensions and IP20 degree of protection make it an ideal choice for mounting on standard 35 mm DIN rails, ensuring easy integration into existing systems.

The Pepperl + Fuchs KFD2-SOT2-EX2 is a testament to the brand's commitment to quality and innovation, offering a reliable and efficient way to manage digital signals in challenging industrial settings.
