Line isolator module A60E-2

Print
The A60E-2 line isolator provides short circuit protection, for analogue addressable loop wiring. Isolators are connected at intervals along the length of the loop, dividing the wiring into a series of separate monitored sections.
Description

A maximum of 16 isolator units can be connected to each loop, (to meet the requirements of EN54 Pt2) which together with isolators at the beginning and end (internal to the panel), enable a maximum of 17 monitored sections. In the event of a short circuit, isolators disconnect only the section of cable between the two isolators, located electrically closest to the fault. Devices outside the disconnected section continue to operate normally.
