EH2304-PR are 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 provides 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.
