The PowerTrans PT-7324 smart switch is designed to meet the demands of power substation automation systems (IEC 61850-3, IEEE1613), traffic control systems (NEMA TS2), and railway applications (EN50121-4). ThePT-7324 is also equipped with smart features, "Class of Service" features suitable for multimedia applications, and port-based VLAN features that can be used to segment your network without being restricted by physical connections. If you do not want to receive too many broadcast packets, the broadcast storm filtering feature will discard broadcast packets if the number of such packets exceeds a threshold in a preset period of time.
