Pepperl Fuchs KFD2-VR2-Ex1.50M Voltage Repeater (181951)

P&F KFD2-VR2-Ex1.50M is a 1-channel voltage repeater that transfers ultra-low voltage signals (±50 mV) from load cells, strain gauges, or inductive oscillation sensors in hazardous areas to the safe zone. Designed for high-precision applications, it offers configurable lead break detection and galvanic isolation between input, output, and power circuits. Housed in a compact 20 mm DIN-rail unit and certified for use up to SIL 2.
