5, 8, 9, and 16-port unmanaged Ethernet switches
EDS-305/308/309/316 Series
Introduction
The EDS-305/308/309/316 Ethernet switches provide an economical
solution for your industrial Ethernet connections. These 5, 8, 9, and
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
Specifications
ATEX Zone 2 standards. The switches comply with FCC, UL, and CE
standards and support either a standard operating temperature range
of 0 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-305/308/309/316 switches can be installed easily on a DIN-
rail or in a distribution box.
›Relay output warning for power failure and port break alarm

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).
