The Moxa PT-7528-12MST-12TX-4GSFP-HV-HV is an advanced IEC 61850-3 and IEEE 1613 Class 2 certified managed Ethernet switch tailored for substation automation and utility networks. Equipped with 12 Fast Ethernet copper ports, 12 Fast Ethernet fibre ports (ST connectors), and 4 Gigabit SFP uplink slots, it supports both backbone and access-layer requirements. Dual isolated 110/220 VDC/VAC power inputs deliver continuous operation and redundancy, making it ideal for mission-critical substations where downtime is unacceptable.
Integrated MMS server functionality, based on IEC 61850-90-4, enables direct SCADA system integration, ensuring interoperability in power automation environments. The switch also supports Moxa’s Noise Guard technology, guaranteeing wire-speed throughput without packet loss even in high-EMC conditions typical of substations. Network resilience is assured with redundancy protocols including Turbo Ring and Turbo Chain (<20 ms recovery), alongside industry-standard RSTP and MSTP.
Comprehensive security features such as IEEE 802.1X authentication, SNMPv3, TACACS+, and RADIUS safeguard against cyber threats, while HTTPS and SSH enable encrypted configuration. QoS, VLAN support, and IGMP snooping ensure the priority delivery of time-critical packets, such as GOOSE and sampled values. Diagnostic tools, including RMON, Syslog, and automatic alarm relay outputs, allow proactive management.
Housed in a fanless aluminium IP40-rated chassis, the PT-7528-12MST-12TX-4GSFP-HV-HV withstands extreme conditions, operating reliably in -40 to 85°C environments. Its compliance with IEC 61850-3, IEEE 1613, and substation EMC standards makes it the optimal choice for power grid modernisation, renewable energy systems, and demanding utility environments.
