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.
