EDS-308Series8-port unmanaged Ethernet switchesFeatures and Benefits•Relay output warning for power failure and port break alarm •Broadcast storm protection•-40to 75°C operating temperature range (-T models)CertificationsIntroductionThe EDS-308Ethernet 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 1Div.2and ATEX Zone 2standards.The switches comply with FCC,UL,and CE standards and support either a standard operating temperature range of 0to 60°C or a wide operating temperature range of -40to 75°C.All switches in the series undergo a 100%burn-in test to ensure that they fulfill the special needs of industrial automation control applications.The EDS-308switches can be installed easily on a DIN rail or in a distribution box.SpecificationsInput/Output InterfaceAlarm Contact Channels1relay output with current carrying capacity of 1A @24VDCEthernet Interface10/100BaseT(X)Ports
