EH2304-PR is with 4 RJ-45 ports for your industrial applications. They are designed to work in the industrial environment, such as in hazardous locations and compliant with CE, FCC, UL, and RoHSII standards.

EH2304-PR protect themselves from receiving over broadcast packets. During normal use, broadcast packets will be forwarded to all ports, except the source port. However, it 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.

EH2304-PR provide two redundant power inputs that can be connected simultaneously to wide-range DC power sources. If one of the power inputs failure, the another live source acts as a backup to provide the EH2304-PR power input automatically.
