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.

Absolutely fantastic service. Rob was very helpful. Great communication. Requested part was shipped in no time.Konrad Eliaszuk
Found the component i was looking for ad a great price. Great support from the staff as I was paying using a wire transfer. - Quick delivery and very good packaging.Adriano Tiberi
Found the part we needed at the best price. Spoke to Rob to make sure the part was actually in stock, as many companies don't actually have the part available to ship. It was in stock ready and the part was checked and shipped and received within a couple of days from their German stock. Would definitely use again and recommend.Chris Sentance
FIRST TIME WORKING WITH MARVO. THEY HAD WHAT I NEEDED AND TOOK GREAT CARE OF ME AND GOT MY ORDER OUT IMMEDITELY. WAS VERY IMPRESSED WITH THE SERVICE AND THE PERSON I SPOKE WITH. I WILL DEFINITELY WORK WITH THEM QGAIN IN THE FUTURE.Robert Cohen
After ordering an urgent part from Marvo i received a great level of customer service and Rob was very helpful.Claire Hinchliff
Excellent service partially from Mark who stayed late to ensure the part arrived with me same day as this was a critical part for me even though this was my first time using Marvo. I will defiantly be using again.Josh Holt
