Pepperl Fuchs KFD0-CS-Ex2.50P Repeater (294983)
P&F KFD0-CS-Ex2.50P is a 2-channel loop-powered analog signal repeater and transmitter power supply for intrinsic safety applications. Designed to isolate and transmit 4–20 mA signals from hazardous areas, it supports 2-wire transmitters in Zones 0/1 and eliminates the need for an external power supply. Housed in a 20 mm-wide DIN-rail module, it offers robust galvanic isolation, reverse polarity protection, and SIL 2 compliance per IEC/EN 61508.
