Pepperl+Fuches KFD0-SD2-Ex1.1180 Solenoid Driver, 1-channel isolated barrier, 24 V DC supply (loop powered), current limit 80 mA at 11 V DC.
This isolated barrier is used for intrinsic safety applications. It supplies power to solenoids, LEDs, and audible alarms located in a 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, 11 V at 80 mA is available for the hazardous area application.
