The Moxa PT-7528-8MSC-16TX-4GSFP-HV-HV is a dual high-voltage input IEC 61850-3 managed rackmount Ethernet switch designed for power substations and mission-critical automation networks. Offering 16 Fast Ethernet copper ports, 8 Fast Ethernet multi-mode SC fibre ports, and 4 Gigabit SFP uplinks, it delivers the flexibility and redundancy needed for complex industrial deployments. Dual 110/220 VDC/VAC inputs guarantee maximum uptime by ensuring continuous power availability.
This model is engineered with Noise Guard technology to maintain zero packet loss at wire speed, even in the high-EMI environments typical of substations. It also features a built-in MMS server aligned with IEC 61850-90-4, enabling seamless SCADA integration and IED interoperability.
Advanced redundancy mechanisms include Turbo Ring and Turbo Chain alongside standard MSTP, RSTP, and STP protocols, achieving recovery times below 20 ms. Strong security is built in, with support for IEEE 802.1X, TACACS+, RADIUS, SSH, and HTTPS. Fibre Check ensures proactive fibre diagnostics and fault prevention, while traffic efficiency is enhanced with QoS, VLANs, IGMP snooping, and bandwidth control.
Capable of operating from -40 to 85°C, the PT-7528-8MSC-16TX-4GSFP-HV-HV is built for the harshest environments. Its combination of dual high-voltage resilience, IEC 61850-3 compliance, and robust cybersecurity makes it an excellent choice for substation operators and industrial users requiring guaranteed uptime and secure, reliable networking.
