The CM797B LAN Isolator module provides 2.5KV electrical isolation between different LAN segments or between the LAN and other modules. The isolator also generates the LAN signals allowing the total LAN length to be increased beyond the standard length of 1200 metres and also provides a 2.5KV isolated 12V @ 250mA power supply which can be used to power keypads or LAN prox readers providing complete electrical isolation for devices located on the outside of buildings etc.
The isolator module help eliminate earth loops in the LAN cabling, improves surge immunity and protects LAN sections from faults and tampering. When the LAN is being connected between separate buildings, an isolator module must be installed in each building to provide the best surge protection.
