MOXA EDS-305 / EDS-308 Series
Industrial 8-port and 5-port Unmanaged Redundant Ethernet Switch
- 10/100BaseT(X), 100BaseFX (Multi/single mode, SC/ST connector)
- Redundant dual 24 VDC power inputs
- Relay output warning for power failure and port break alarm
- Broadcast storm protection
- Transmits VLAN tag packets transparently
- -40 to 75¢ªC operating temperature range (T models)
- Rugged hardware design well suited for industrial environments
The EDS-305/308 are 5-port 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 I, Div. 2/ATEX). The switches comply with FCC, TÜV, 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 switches can be installed easily on a DIN-rail or in a distribution box.
