Digitus Gigabit Ethernet PoE splitter priemyselný 60W IEEE 802.3af 802.3at 802.3bt

The Digitus Gigabit Ethernet PoE Splitter DN-651140 converts PoE power delivered over an RJ45 cable into a 12V DC output for powering devices in Gigabit Ethernet environments. The splitter supports IEEE 802.3af, 802.3at and 802.3bt standards, accepts 36–57 VDC input and provides up to 51 W (typical configuration) or up to the model's rated output for industrial applications. It includes one PoE RJ45 port (data + power in), one LAN RJ45 port (data only) and a DC output connector for the powered device.

Advantages

The DN-651140 supports Gigabit pass-through data rates and both Alternative A and Alternative B PoE connections, enabling compatibility with a wide range of PSE equipment. Its wide input voltage range (36–57 VDC) reduces the need for external components, and the device is rated for extended operating temperatures and humidity ranges suitable for industrial use. Compact dimensions and included DC cable simplify installation.

Suitable for

• Powering IP cameras, access points and networked sensors that require 12V DC
• Industrial network equipment where Gigabit data and PoE power conversion are needed
• Deployments that require IEEE 802.3af/at/bt compatibility and Alternative A/B support

How to use

Connect a PoE-enabled RJ45 cable from a compatible PoE switch or injector to the PoE port on the DN-651140. Connect the LAN RJ45 port to the downstream network device if data pass-through is required. Use the DC OUT connector to supply the target device with 12 VDC. Ensure the PSE (switch or injector) supports the required IEEE PoE class and that cable runs do not exceed recommended lengths for the chosen data rate.

Recommendations

For reliable operation, use Cat5e or Cat6 cable for Gigabit links, verify PSE compatibility with IEEE 802.3bt if maximum power is required, and keep cable lengths within 100 m. Install in environments within the specified temperature and humidity ranges and avoid exposure to condensation.
