Industrial managed PoE++ switches equipped with Ethernet ports, SFP slots, plus RS485 bus, digital/alarm inputs and relay outputs. Event management, which is part of advanced management, makes these switches ideal 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 120W. All inputs and outputs are equipped with surge protectors, making the switches suitable for deployment even in very harsh environments.
