Moxa EDS-309-3M-SC 9-port unmanaged Ethernet switches

Features and Benefits

Relay output warning for power failure and port break alarm
Broadcast storm protection
-40 to 75°C wide operating temperature range (-T models)

Introduction

Moxa EDS-309-3M-SC 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. Moxa EDS-309-3M-SC switches can be installed easily on a DIN rail or in a distribution box.
