The Moxa PT-7528-20MSC-4TX-4GSFP-HV-HV is a dual high-voltage input managed Ethernet switch built for IEC 61850-3 substations and critical infrastructure networks. It features four copper Fast Ethernet ports, 20 multi-mode SC fibre ports, and 4 Gigabit SFP uplinks, providing extensive fibre connectivity with resilient power redundancy.
Designed to meet IEC 61850-3 and IEEE 1613 standards, the PT-7528 withstands extreme EMI and electrical disturbances. Noise Guard technology ensures wire-speed zero packet loss, while the integrated MMS server enables IEC 61850-90-4 SCADA data modelling for seamless interoperability with automation systems.
Turbo Ring and Turbo Chain redundancy provide <20 ms failover, complemented by STP, RSTP, and MSTP support. Fibre Check allows real-time fibre diagnostics, reducing downtime and ensuring consistent network performance. VLANs, quality of service, IGMP snooping, and port trunking enhance determinism and throughput in complex industrial networks.
, thereby improving overall network performance. Cybersecurity is robust, with IEEE 802.1X, RADIUS, TACACS+, SSH, and HTTPS safeguarding access. SNMPv3, RMON, and Syslog support monitoring, simplifying system management across large deployments.
With dual 110/220 VDC/VAC inputs, the PT-7528-20MSC-4TX-4GSFP-HV-HV provides continuous uptime for mission-critical applications. Its rugged -40 to 85°C rating makes it a dependable choice for substations, utilities, and transport operators seeking maximum reliability and fibre-rich networking
