Description
This isolated barrier is used for intrinsic safety applications.
The device transfers DC signals of fire alarms and smoke alarms from the hazardous area to the non-hazardous area.
The device can also be used to control I / P converters, valves, indicators, and audible alarms.
A reverse polarity protection prevents damage to the device caused by faulty wiring.
The device is loop powered. From the control side no additional power supply has to be connected.
Use the technical data to verify that proper voltage is available to the field devices.
The Conventional Galvanic Barrier is DIN-Rail mounted and installed in the safe area to ensure system integrity. The device also enables compliance with the ATEX directive.
