5, 8, 9, and 16-port unmanaged Ethernet switches

EDS-305/308/309/316 Series

Introduction

The EDS-305/308/309/316 are 5, 8, 9, and 16-port Ethernet switches

that provide 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 switches

are designed for harsh industrial environments, such as in hazardous

locations (Class I, Div. 2/ATEX). The switches comply with FCC, UL,

and CE standards, and come in two model types: standard operating

temperature range models (0 to 60°C) and wide operating temperature

range models (-40 to 75°C). Both models 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.
