XP95 DIN-Rail Dual Isolator

Product Overview

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

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

Features

  • 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 sie of the osolator, its yellow LED is illuminated.
