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


The EDS-309 are 9-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 / ATEX Zone 2). 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-309 switches can be installed easily on a DIN-rail or in a distribution box.


Is Your Network Infrastructure Ready for the IIoT?


The Industrial Internet of Things (IIoT) trend aims to improve efficiency and productivity by connecting different devices together as well as collecting and analyzing large volumes of data to offer accurate information. However, before reaping the benefits of the IIoT, users need to ensure that the correct infrastructure is in place. To make sure your network is ready for the IIoT, check out five of the most frequently mentioned questions..........more
