Introduction<\/h3>\n

The EDS-308 Ethernet switches provide an economical solution for your industrial Ethernet connections. These 8-port switches come with a built-in relay warning function that alerts network engineers when power failures or port breaks occur. In addition, the switches are designed for harsh industrial environments, such as the hazardous locations defined by the Class 1 Div. 2 and ATEX Zone 2 standards.<\/p>\n
