Power Substation Switches

Ethernet switches are hardware devices that centralize communications among multiple connected Ethernet devices, such as computers Wi-Fi access points, IoT devices and servers, to one local area network (LAN). They manage the flow of data across the network by transmitting received network packets to one or more devices for which the packets are intended. Ethernet switches can identify every device connected to them and direct the traffic flow of the devices, which ensures the efficiency and security of the network.
Unmanaged Ethernet switches have fixed configurations that cannot be changed. They are plug-and-play devices that are easily added to small networks and don’t need any special set-up. Managed Ethernet switches can manage, configure and monitor the settings of a LAN. They can control LAN traffic, prioritize certain channels and create new virtual LANs to keep smaller groups of devices segregated. Managed switches offer redundancy features that duplicate and recover data in the event of a device or network failure and priority SNMP allows for remote troubleshooting of the network, making it easier to check for issues impacting performance and implementing fixes.
Moxa PT-7528 Series is designed for power substation automation applications that operate in harsh environments. It features critical packet prioritization, a built-in MMS server and a configuration wizard designed specifically for substation automation. The PT-7528 Series supports Moxa’s Noise Guard technology, is compliant with IEC 61850-3, and its EMC immunity exceeds IEEE 1613 Class 2 standards to ensure zero packet loss while transmitting at wire speed.
Moxa PT-7710 is designed for power substation automation systems and railway applications. The PT-7710’s Gigabit and Fast Ethernet backbone, redundant ring, and 12/24/48 VDC redundant power inputs increase the reliability of the communications and reduce cabling and wiring costs.
Moxa PT-G503-PHR-PTP Series redundancy boxes ensure system availability and data integrity for critical applications in electrical substations and process automation systems that require zero recovery time redundancy.
