Introduction
The EDS-309 Ethernet switches provide an economical solution for your industrial Ethernet connections. These 9-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.
The switches comply with FCC, UL, and CE standards and support either a standard operating temperature range of -10 to 60°C or a wide
operating temperature range of -40 to 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-309 switches can be installed easily on a DIN rail or in a distribution box.
