Function

This isolated barrier is used for intrinsic safety applications.

The device supplies power to solenoids, LEDs and audible alarms located in the explosion-hazardous area.

The device is controlled with a loop powered signal or a bus powered logic signal.

The device is immune to the test pulses of various control systems.

The device simulates a minimum load at the input. The minimum load is set via the mode of operation. In the loop-powered mode of operation, a minimum load of 20 mA is simulated. In the bus-powered mode of operation, a minimum load of 5 mA is simulated.

The line fault transparency function can display a line fault in the field by a change in impedance at the switching input of the solenoid driver.

A fault is indicated by LEDs and output via a fault indication output.
