Pepperl-Fuchs KKFD0-CS-EX2.51P Galvanic Isolator - Dual Channel

The Pepperl+Fuchs KFD0-CS-Ex2.51P is a dual-channel intrinsically safe current driver and repeater designed to transfer analogue signals safely between hazardous and non-hazardous areas.

It is commonly used in fire alarm, smoke detection and industrial process control applications where reliable isolation of 0–40 mA signals is required. The unit provides galvanic isolation between the field and control circuits while remaining loop powered, eliminating the need for an additional power supply on the safe area side.

With SIL 2 (SC 3) certification, reverse polarity protection and approvals for use in Zone 0, Zone 1 and Zone 2 hazardous areas, the KFD0-CS-Ex2.51P is well suited to safety-critical installations involving detectors, I/P converters, valves, indicators and audible alarms.
