Industrial managed PoE+ switches LAN-RING equipped with Ethernet ports, SFP slots and in addition RS485 bus, digital / alarm inputs and relay output. Event management, which is part of advanced management, makes these switches the ideal solution for applications with high demands on security and flexibility of the equipment used. The switches support redundant MESH / RING topologies with up to 30ms link recovery. Thanks to the highly resilient hardware, the switches can be deployed in a wide operating temperature range of -40 to 70°C with a maximum PoE power of 90W.
