Hallitsematon kytkin Digitus DN-651121 8 porttia Gigabit Ethernet PoE

The Digitus DN-651121 is an unmanaged 8-port Gigabit Ethernet PoE switch designed for industrial environments. It provides eight 10/100/1000Base-TX PoE ports and supports IEEE 802.3af/at Power over Ethernet, delivering up to 30 W per port. Built for harsh conditions, the switch is DIN-rail mountable and operates across a temperature range of -40°C to 80°C, making it suitable for use in transport, production and safety monitoring applications.

Advantages

The DN-651121 offers robust, maintenance-free operation as an unmanaged switch with a switching capacity of 16 Gbit/s and a MAC address table of 4096 entries for efficient Layer 2 traffic handling. Its PoE capability and 48–57 V DC input allow powering IP cameras, access points and other PoE devices directly from the switch. Compact DIN-rail mounting and a durable design resistant to moisture, vibration and wide temperature fluctuations simplify installation in industrial racks and cabinets.
