The Moxa PT-7528-16MSC-8TX-4GSFP-HV-HV is a dual high-voltage input managed Ethernet switch designed for substation automation and mission-critical networks. With 8 Fast Ethernet copper ports, 16 multi-mode SC fibre ports, and 4 Gigabit SFP uplinks, it provides a robust, fibre-heavy backbone for power utilities and industrial automation.
Certified to IEC 61850-3 and IEEE 1613 standards, this switch withstands EMI-rich environments typical of substations. Noise Guard technology eliminates packet loss, while its built-in MMS server enables IEC 61850-90-4-based SCADA integration.
The switch delivers high reliability through Turbo Ring and Turbo Chain (<20 ms recovery), alongside STP, RSTP, and MSTP. Fibre Check ensures proactive monitoring of fibre health, reducing service disruptions. Operators also benefit from VLAN support, QoS, IGMP snooping, and bandwidth trunking for efficient traffic handling.
Security is a core feature, with TACACS+, RADIUS, SSH, HTTPS, and IEEE 802.1X authentication ensuring robust access control. SNMPv3, RMON, and Syslog allow centralised management and monitoring.
With a wide operating temperature of -40 to 85°C, the PT-7528-16MSC-8TX-4GSFP-HV-HV is built for reliability in the toughest substation and industrial environments. Dual HV inputs ensure continuous uptime, making it an ideal solution for power distribution and transport infrastructure requiring uncompromising availability.
