Pepperl+Fuchs Intrinsic Safety Barriers K-System Solenoid Driver KFD2-SL2-Ex1 arrived.

Time: 2020年04月14日

Feature: 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: KFD2-SL2-Ex1

· 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 kΩ for lead breakage or < 50 Ω for short circuits a line fault is detected.

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