Switch no gestionado Digitus DN-651133 8 puertos Fast Ethernet industrial 1 uplink SFP

The DN-651133 is an industrial-grade unmanaged Ethernet switch with 8 Fast Ethernet (10/100) RJ45 ports and 1 100 Mbps SFP uplink. Designed for harsh environments, it provides non-blocking wire-speed performance, Power over Ethernet (IEEE 802.3af) support and operates from a DC 48–57 V supply with reverse-polarity protection. The switch features a compact IP40 housing, DIN-rail mounting and LED indicators for straightforward installation and status monitoring.

Advantages

The device uses high-quality photoelectric integrated modules to ensure stable optical and electrical characteristics, reliable data transmission and long service life. It supports full- and half-duplex modes with automatic negotiation, automatic MDI/MDIX on network ports, and an internal store-and-forward mechanism that supports multiple protocols. The switch is built to industrial standards with an average trouble-free operating time exceeding 300,000 hours and offers surge protection on the power input (5000 A, 8/20 µs). It also tolerates wide temperatures from -40 °C to 80 °C.

How to use

Mount the DN-651133 on a standard DIN rail inside a control cabinet or other suitable enclosure with IP40 protection. Connect the DC 48–57 V power supply to the designated terminals, observing polarity; the device includes reverse-polarity protection. Plug Ethernet devices into the RJ45 ports; PoE-capable ports will provide power to compatible devices automatically. Use the SFP slot for fiber uplink as needed. Monitor link and activity via the front-panel LEDs to verify connections and status.

Recommendations

Place the switch in a ventilated location within its specified temperature range and protect it from direct moisture. Use appropriate surge protection on incoming power and fiber lines when deploying in high-risk outdoor or industrial environments. Verify PoE power budget against connected devices to ensure reliable operation.
