Industrial Ethernet Switches are designed to operate in harsh environments. The specifications of Industrial Ethernet switches (temperature, shock, vibration) meet or exceed the equipment being connected (PLC’s, Ethernet I/O, HMI’s). Most commercial Ethernet switches have commercial temperature ratings (0oC to 40oC), and do not publish shock and vibration specs. Industrial Ethernet switches are housed in industrial style steel enclosures using Din-Rail or panel mounting. Most commercial switches and media converters cannot mount conveniently inside equipment enclosures. Industrial Ethernet switches have redundant power inputs. Commercial switches rely on a single power supply to power the switch, while Industrial switches typically run off DC power. This allows the weakest link (the power supply) to have a hot standby back up, insuring maximum up time. Industrial Ethernet switches carry a Class I Div. 2, group ABCD rating while the commercial counterparts do not. This allows the Industrial Ethernet switches to operate where explosive gases are being used.
