Industrial 8-Port Switch

The Brainboxes SW-508 is an unmanaged Ethernet switch with eight galvanically isolated ports. It is built for engineers and integrators who need reliable network connectivity on the factory floor, in vehicles or in marine environments where standard commercial gear cannot survive.

Thermals and Power

The unit operates across an industrial temperature range of -40°C to +80°C (-40°F to 176°F) with no moving parts. A dual-input redundant power supply accepts a wide voltage range, drawing optimised power based on link status and allowing supply from USB or 24V factory systems via a removable terminal block.

Galvanic Isolation

Every port provides galvanic isolation, protecting connected equipment from ground loops and voltage spikes common in industrial settings. Buyers who require managed features such as VLANs, SNMP or port mirroring should select a managed switch instead.

Questions about this item

How is the removable power terminal with numbered pins wired for the dual redundant inputs?

Connect each supply to the labelled pins on the removable terminal block; the switch accepts USB or 24 V sources and the numbered pins make it straightforward to wire both inputs without crossing them.

What maintenance does the galvanically isolated port design require over time?

No routine maintenance is needed for the isolation itself; keep the unit within its -40 °C to +80 °C operating range and verify that the redundant power feeds remain secure.

At what temperature does the switch hit its thermal limit during continuous operation?

The specified industrial temperature range tops out at +80 °C (176 °F); sustained ambient heat beyond that is the first limit you will encounter.
