The XP95 DIN-Rail Isolator - Dual Channel provides two independent isolators which sense and isolate short circuits on Discovery and 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 exists on either side of the isolator, its yellow LED is illuminated.
The unit is intended for use in systems using the Apollo Series 90, XP95 or Discovery protocols.
Under normal operating conditions, a low imped-ance is present between the two negative terminals of each iso la tor channel so that power and signals are passed to the next base in line.
