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 a logic signal. The input has 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, 11.2 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.
During an error condition, the fault indication output de-energizes.
A fault is signalized by LEDs and a separate collective error message output.
