P+F KFD2-VM-EX1.35 Solenoid Driver – KFD2 Series Intrinsically Safe Signal Conditioner
Imagine a critical process valve in a Zone 1 hazardous area failing to respond — not because of a mechanical fault, but because the solenoid driver in the safe area lost its ability to deliver a reliable, isolated switching signal. In petrochemical plants, offshore platforms, and pharmaceutical production lines, this single point of failure can trigger emergency shutdowns, production losses, and serious safety incidents. The P+F KFD2-VM-EX1.35 exists precisely to eliminate this risk, providing a robust, certified interface between your safe-area control system and Ex-zone solenoid valves.
Within the Pepperl+Fuchs KFD2 product family — one of the most trusted NAMUR-compliant signal conditioner series in global process automation — the KFD2-VM-EX1.35 occupies a specialized position as a single-channel solenoid/valve driver designed for intrinsically safe applications. Pepperl+Fuchs, headquartered in Mannheim, Germany, has been a benchmark supplier for explosion protection and industrial sensing technology for over 75 years, and the KFD2 series reflects that engineering heritage with its compact DIN rail form factor, universal 24 V DC power rail compatibility, and broad international approvals.
