Inner Range - Concept: LAN Isolator

Control

Terminals

The LAN Isolator affords a Concept system with optical isolation of LAN wiring with an optional LAN 'loop' mode. The elimination of electrical connection between LAN sections serves as a means to break earth loops as well as extending the length of the LAN.

In addition to this, the LAN Isolator monitors its LAN sections and can isolate sections of the LAN where problems are discovered. Also provided are outputs to indicate the status of the LAN allowing LAN section status and alarms to be reported as required.

Features:

5kV isolation between LAN sections
Can help eliminate earth loops in the LAN
Improved anti-surge protection
Improved signal to noise ratio over longer cable runs
Two downlink ports on each unit allow monitored 'Loop' wiring or two separate downlink 'Branches'
Protects sections of the LAN from faults or tampering in other sections
'Loop Fail' and 'Branch Isolated' alarm outputs can be wired into any standard zone input
Plastic enclosure supports base and cover tamper switches
