Function
This isolated barrier KFD2-SL2-Ex1 is used for intrinsic safety applications. It supplies power to solenoids, LEDs, and audible alarms, located in a hazardous area. It is controlled via a logic signal. The input has two defined states: 1-Signal = 16 V DC ... 30 V DC, 0- Signal = 0 V DC ... 5 V DC. The current consumption of the input is about 3 mA. Pepperl+Fuchs isolated barrier KFD2-SL2-Ex1
At full load, 11.7 V at 45 mA is available for the hazardous area application.
If the field impedance is > 10 kΩ for lead breakage or < 50 Ω for short circuits a line fault is detected.
A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
