The Pepperl + Fuchs KFD2-CD2-EX2 is a high-performance isolated barrier designed for intrinsic safety applications within industrial settings. This robust component is engineered to facilitate the transfer of 4 mA to 20 mA signals from safe areas to I/P converters, electrical valves, and positioners located in hazardous areas. It boasts a 2-channel isolated barrier system and is powered by a 24 V DC supply via the Power Rail.
With an impressive accuracy of 0.05%, the KFD2-CD2-EX2 ensures precise signal transmission and is capable of driving current outputs up to a 700Ω load. This makes it an ideal choice for applications requiring reliable and accurate control over actuators and instrumentation in potentially explosive environments.
The unit is designed to present a similar resistance to the control side in the event of an open or high resistance field circuit, which allows for line fault detection by the control system. This feature enhances the safety and reliability of the system it is integrated into. Additionally, the device is compliant with SIL 2 according to IEC 61508, indicating a high level of functional safety.
Constructed with a focus on durability and ease of use, the KFD2-CD2-EX2 comes with removable terminals for straightforward installation and maintenance. Its compact dimensions and IP20 degree of protection make it suitable for mounting on a 35 mm DIN rail, ensuring it fits seamlessly into a variety of control cabinets and panels.
The KFD2-CD2-EX2 is a testament to Pepperl + Fuchs' commitment to quality and safety in the field of process automation and control. It is a reliable solution for professionals looking to maintain operational integrity and safety in challenging industrial environments.

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
Extremely Helpful. Shipped me a replacement unit next day and i was up and running within 24 hours. Replacement new from machinery manufacturers was on a 7 day lead time.Sean Conlin
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
