Industrial 4-Port Switch

The Brainboxes SW-504 is an unmanaged Ethernet switch built for harsh environments. It targets engineers and integrators deploying networks on factory floors, in vehicles or in marine settings where standard hardware cannot survive.

Galvanic Isolation & Power Flexibility

Every port is galvanically isolated to protect connected equipment from ground loops and surges. A removable terminal block with numbered pins accepts dual redundant inputs across a wide voltage range, allowing power from USB sources or 24 V industrial supplies.

Replaces Basic Office Switches

This unit replaces commercial switches that lack isolation, wide-temperature ratings or redundant power. The upgrade is worth it when downtime caused by electrical noise, extreme cold or heat, or single-point power failure is unacceptable.

Questions about this item

What Ethernet standard does the SW-504 use and what speed does it cap at?

The SW-504 is an industrial 4-port unmanaged Ethernet switch; each port runs at standard Ethernet speeds without software configuration.

What physical space and mounting does the SW-504 need?

Weighing 0.2 lbs, the compact unit fits tight DIN-rail or panel spaces and uses a removable terminal block with numbered pins for secure wiring.

How is the SW-504 installed and which step do installers often miss?

Connect the dual redundant supply to USB or 24 V factory power, then link devices; the step often missed is matching each wire to the numbered terminal pins.
