Certifications
Introduction
The EDS-316 Ethernet switches provide an economical solution for your industrial Ethernet connections. These 16-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-316 switches can be installed easily on a DIN rail or in a distribution box.

Note: When connecting a single-mode fiber transceiver, we recommend using an
attenuator to prevent damage caused by excessive optical power.
Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link
budget (dB) > dispersion penalty (dB) + total link loss (dB).
