Unmanaged switch Digitus DN-651109 4-poorts Gigabit Ethernet PoE

The DIGITUS DN-651109 is an unmanaged industrial Gigabit Ethernet PoE switch built for harsh environments. It offers four 10/100/1000Base-TX PoE ports and two 1000Base-X SFP uplink ports, supports IEEE 802.3af/at PoE with up to 30 W per port, and accepts a DC input voltage of 48–57 V. Designed for operation in a wide temperature range (-40 °C to 75 °C) and vibration-prone locations, the switch is suitable for continuous use in transport, production, traffic and security surveillance systems. DIN-rail mounting and plug-and-play installation simplify integration into industrial networks.

Advantages

The switch provides Gigabit connectivity combined with PoE power delivery, enabling network devices to receive both data and power over a single cable. Its rugged design and extended operating temperature range allow reliable performance in demanding industrial conditions. Two SFP uplink ports add flexibility for fiber connections, while the unmanaged architecture ensures simple, maintenance-free operation.

Suitable for

• Industrial automation networks
• Traffic monitoring and control systems
• Security and surveillance camera installations
• Public transport and vehicle-mounted networks

How to use

Mount the switch on a DIN rail in a suitable industrial enclosure or cabinet. Connect network devices to the four Gigabit PoE RJ-45 ports using Ethernet cables; compatible PoE devices will receive power automatically according to IEEE 802.3af/at. Use the SFP uplink ports for fiber connections to core switches or long-distance links. Provide DC power within the specified 48–57 V range to the power input. The device operates unmanaged, so no configuration is required—simply connect cables and power for immediate use.

Recommendations

Install the switch in a ventilated, dust-reduced location and ensure the DC power supply meets the voltage and current requirements for all connected PoE devices. Use quality shielded cables in noisy electrical environments and test fiber links after SFP module insertion to confirm connectivity.
