While there are many similarities between commercial and industrial Ethernet network, there are also crucial difference. ThestandardcommercialEthernetcannotsimplybe“teleported”intoanindustrialenvironmentandsucceed. Therefore the reason to use Industrial Ethernet product instead of commercial Ethernet product are due to
Rugged Enclosure Design
Operate at wider Temperature range - wider and higher, typically -10 C to +60 C or -40 C to +75 C
Redundant power sources for high reliability
Power supply fault relay output (N/C, opens on fault)
Input power surge protection and Reverse power polarity protection
