ENQUIRE NOWProduct Overview
The Pepperl+Fuchs KFD0-SD2-Ex2.1045 is a 2-channel isolated barrier solenoid driver. It is loop powered from the 24 V DC control signal and drives intrinsically safe solenoid valves, alarms and LEDs in the hazardous area, with each output current-limited to 45 mA at 10 V DC.
Because it is loop powered, no separate supply is required. The module is ATEX and IECEx certified for Ex ia outputs and is suitable for applications up to SIL 3 to IEC/EN 61508, making it a common choice for on/off valve actuation in safety and process control systems.

Specifications are taken from Pepperl+Fuchs manufacturer data. Always confirm critical values — particularly hazardous-area and functional-safety data — against the current datasheet, certificates and instruction manual before installation.
Applications
- Intrinsically safe solenoid valves on actuated valves
- Ex-area alarm sounders and indicator LEDs
- Emergency shutdown (ESD) valve actuation
- SIL 3 final element loops
Installation and Compatibility
DIN rail mounting; the unit is loop powered from the control-side signal on terminals 7, 8 / 8, 9 — no Power Rail supply. Solenoids connect to 1+/2- and 4+/5-. Verify the solenoid's Ex i parameters and minimum operating current against the barrier output data.
