Details: KFD0-SD2-Ex2.1545


This isolated barrier is used for intrinsic safety applications.

The device supplies power to solenoids, LEDs and audible alarms located in the explosion-hazardous area.

It is loop powered, so the available energy at the output is received from the input signal. The output signal has a resistive characteristic. As a result the output voltage and current are dependent on the load and the input voltage.

At full load, 15 V at 45 mA is available for the hazardous area application.

A fault is signalized by LEDs.
