The Moxa PT-7528-8MST-16TX-4GSFP-HV-HV is a dual high-voltage input managed Ethernet switch tailored for IEC 61850-3 substation and industrial networks. With 16 Fast Ethernet copper ports, 8 Fast Ethernet multi-mode ST fibre ports, and 4 Gigabit SFP uplinks, it combines high port density with resilient power redundancy for critical operations. Dual 110/220 VDC/VAC inputs safeguard against single power source failures, ensuring maximum uptime.
Its Noise Guard technology guarantees zero packet loss under high EMI conditions, maintaining reliable data transmission. A built-in MMS server, based on IEC 61850-90-4, simplifies SCADA integration and supports efficient communication with intelligent electronic devices.
For fault-tolerant networking, the switch leverages Moxa’s Turbo Ring and Turbo Chain with sub-20 ms recovery, alongside industry standards STP, RSTP, and MSTP. Security is reinforced with IEEE 802.1X, TACACS+, RADIUS, SSH, and HTTPS protocols. Fibre Check diagnostics, VLAN segmentation, QoS prioritisation, and IGMP snooping provide efficient traffic control and early fault detection.
Designed for rugged environments, the PT-7528-8MST-16TX-4GSFP-HV-HV is rated for -40 to 85°C and fully compliant with IEC 61850-3 and IEEE 1613. Its dual HV power resilience, hardened cybersecurity, and flexible fibre connectivity make it an ideal backbone switch for substations, railway control, and industrial automation requiring uncompromised reliability.
