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 with a loop powered control signal, switch contact, transistor, or logic signal. At full load, 12 V at 40 mA (with 55 mA current limit) is available for the hazardous area application. Line fault detection of the field circuit is indicated by a red LED and an output on the fault bus. This device mounts on a HiC termination board.
