Pepperl+Fuchs KCD2-SR-EX1.LB Switch Amplifier Part No. 70112151 is a 1-channel isolated switch amplifier designed for safe signal transmission between hazardous-area field devices and safe-area control equipment. It is used in industrial automation systems where NAMUR sensors or dry contact inputs must be conditioned, isolated, and converted into a reliable relay contact output for PLC, DCS, and safety loop integration. This industrial grade module features line fault detection for open or shorted field wiring, helping maintenance teams identify signal issues quickly and improve system reliability. Its signal splitter functionality allows one input to drive two outputs, making it useful in applications that require signal duplication without compromising electrical isolation. The unit is SIL 2 capable according to IEC 61508, which makes it suitable for safety-related instrumentation and intrinsically safe interface applications. The KCD2-SR-EX1.LB is built in a slim 12.5 mm DIN-rail mount housing, supporting efficient panel design where space is limited. It operates from a 24 V DC power supply with a 19…30 V DC range and supports switching frequencies up to 10 Hz. The relay output is suitable for AC/DC loads, with a typical 2 A rating depending on voltage, providing dependable switching performance for control circuits. With a wide operating temperature range of –40°C to +70°C and IP20 housing protection, this module is suitable for harsh industrial environments. Common applications include monitoring valve positions, switches, proximity sensors, and other hazardous-area field signals in process automation and safety systems. For wholesale, bulk order, OEM, and factory direct sourcing, this Pepperl+Fuchs switch amplifier is export-ready and available with a minimum order quantity of 1 unit. It is a practical procurement choice for electrical distribution, automation integrators, and maintenance teams seeking a trusted isolated barrier for industrial signal interfacing.
