XP95 Addressable DIN-Rail Dual Isolator

The XP95 DIN-Rail Dual Isolator provides, in one housing, two independent isolators that sense and isolate short-circuits on XP95 loops and spurs.

The isolators are loop-powered and are polarity sensitive. A maximum of twenty XP95 detectors may be installed between isolators.

When a short circuit condition exits on either side of the isolator, its yellow LED is illuminated.

The unit is intended for use in systems using the XP95 or Discovery protocols.
