PEPPERL+FUCHS Solenoid Driver KFD2-SL2-Ex1 Intrinsic Safety Barriers 

Isolated Barriers K-System Solenoid Driver 

Solenoid Driver KFD2-SL2-Ex1

1-channel isolated barrier

24 V DC supply (Power Rail)

Output 45 mA at 11.7 V DC

Logic input, non-polarized

Line fault detection (LFD)

Up to SIL 2 acc. to IEC 61508

Function : 

This isolated barrier is used for intrinsic safety applications. The device supplies power to solenoids, 

LEDs and audible alarms located in a hazardous area. 

It is controlled via logic signals. The inputs have 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. At full load, 11.7 V at 45 mA is available for the hazardous area application.

If the field impedance is > 10 kolihm for lead breakage or < 50 kolihm for short circuits a line fault is detected. 

A fault is signalized by LEDs and a separate collective error message output.
