CM797B LAN Isolator Module with Isolated Power Supply
The CM797B is a Bosch RS485 LAN isolator module with isolated power supply. With 2.5 kV electrical isolation between LAN segments or between the LAN and other modules, LAN signal regeneration, and an isolated 12 V supply for keypads or LAN prox readers.
It is useful where LAN cabling crosses between buildings, reaches external wall-mounted devices or exceeds standard cable-run expectations. Reduce earth loop issues and supports surge-immunity planning by electrically separating LAN sections.
