The EDS-308-MM-ST-T is 8-port Ethernet Switch that provides an economical solution for your industrial Ethernet connections. The built-in relay warning function alerts network engineers when power failures or port breaks occur, and the EDS-308-MM-ST-T Ethernet Switches are designed for harsh industrial environments, such as in hazardous locations (Class I, Div. 2/ATEX). The EDS-308-MM-ST-T Ethernet Switches comply with FCC, TÜV, UL, and CE standards, and come in the wide operating temperature range model (-40 to 75°C). They undergo a 100% burn-in test to ensure that they fulfill the special needs of industrial automation control applications. The EDS-308-MM-ST-T Ethernet Switches can be installed easily on a DIN-rail or in a distribution box.
