KFD2-SL2-Ex2.B

2-channel isolated barrier

<

24 V DC supply (Power Rail)

<

Output 45 mA at 11.7 V DC

<

Logic input, non-polarized

<

Up to SIL 2 acc. to IEC 61508

<

without lead monitoring

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.
