The KCD2-SR-Ex1.LB is a single-channel isolated barrier with 24 V DC power supply that supports NAMUR dry contacts or inputs. It is equipped with a line fault detection (LFD) function and relay outputs. This ensures safe signal transmission in hazardous areas such as oil and gas fields. Its compact design and high reliability make it ideal for use in narrow spaces and hard-to-reach locations. Easy installation and maintenance guarantees a long service life and efficient operation in harsh environments.
