Product Description

The Isolator module is an automatic device that isolates a part of the loop
by opening when the line voltage drops below 14Volts. These modules
should be spaced between groups of sensors or modules in a loop to
isolate the faulty area from the rest of the loop. If a short occurs between
any two isolators, then both isolators immediately switch to an open
state and isolate the devices between them. The remaining units on the
loopcontinue to fully operate. Recommended to connect a maximum of
20 devices to each isolator. The module blinks indicating normal status
