Ethernet Switch Industry, 4 Port

Article number: 55604

  • Ethernet Switch Industry

Networking in the control cabinet incl. 24V or PoE injection/extraction

The compact Industry-Switch connects up to four network components in the control cabinet. The Switch itself is powered via PoE or with 24-48V and can also power the connected components using PoE injection or a voltage output (PoE extraction).

Properties:Show more


  • 4x Ethernet 10/100BaseT

Management and connectivity:

  • Port mirroring for network recordings
  • Industrial grade with
    • noise immunity in accordance with EN 61000-6-2
    • Housing for DIN rail mounting
    • Operating temperature range 0...70°C

Power supply:

  • Special functions for PoE or 48V supply:
    • Pass-through / injection: The switch can power up to three PoE-capable terminal devices
    • Extraction: The switch decouples 24V DC / 10W from PoE for powering non-PoE devices
  • External
    • Screw terminals, 24 - 48V DC
    • Use as PoE injector only possible with 48V DC

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance for industrial environments
    • Low noise emission for residential and business areas
  • 5 year guarantee

Sample applications:Show more

Narrow network expander:
A nearly full control cabinet and you still have 2-3 more network terminal devices to connect? The compact, 22mm wide switch is ideal for networking Com-Servers, Web-IOs, Web-Thermographs, USB Servers or other Ethernet terminal devices.

Non-PoE network camera in a PoE network:
The additional power output provides up to 500mA at 24V. This means for example a non-PoE network camera can be integrated into a PoE network without the need for an additional external power supply.
