The EH2005  Series features  a 5-port Ethernet switches with 4 x RJ-45 ports and one optic ST/SC port for your industrial applications. The EH2005  series has been designed for industrial environments, such as in hazardous locations, where it complies with FCC, TUV, UL, and CE standards.

The EH2005  Series  protects itself from receiving too many broadcast packets. During normal use, broadcast packets will be forwarded to all ports except the source port. However, EH2005 will discard broadcast or multicast packets if the number of those packets exceeds a threshold in a preset period of time. When the preset period expires (about 800ms), it will then resume receiving broadcast or multicast packets until the threshold is reached again.

The EH2005  Series provides two redundant power inputs that can be connected simultaneously to wide-range DC power sources. If one of the power inputs fails, the other live source acts as a backup to provide the EH series' power needs automatically.
