Features and Benefits

 

Introduction

The EDS-305/308 are 5 and 8-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 1 Div. 2/Zone 2). The switches comply with FCC, TÜV, UL, and CE standards, and come in two model types: standard operating temperature range of 0 to 60°C, and extended operating temperature range of -40 to 75°C. Both models undergo a 100% burn-in test to ensure that they fulfill the special needs of industrial automation control. The EDS-305/308 series switches can be installed easily on a DIN-Rail or in a distribution box.
