Function

This isolated barrier is used for intrinsic safety applications. It supplies power to solenoids and other similar loads.

It is controlled by two "OR" and one "AND" configured logic input.

At full load, 15.3 V at 17 mA is available for the hazardous area load. The output signal has a resistive characteristic.

An override/test jack feature is available on the front plate of the device.

By engaging the service plug, the logic inputs are bypassed and the output is energized. The operation of this test feature is indicated by a red LED.
