The Pepperl+Fuchs KFD0-SD2-Ex2.1045 is a dual-channel galvanic isolator and solenoid driver designed for intrinsically safe operation in hazardous areas.

It provides a secure interface between safe-area control systems and field devices such as solenoids, LEDs, and audible alarms in Zone 0, 1, or 2 environments.

Loop-powered from the input signal, it delivers a controlled resistive output up to 10 V at 45 mA, ensuring safe and reliable actuation of hazardous-area devices.

Certified to SIL 3 (IEC/EN 61508) and approved under ATEX, IECEx, FM, and UL standards, it is ideal for safety-critical applications including process control, fire protection, alarm signalling, and industrial automation.

Its slim DIN-rail design enables easy installation in compact control panels.
