The PT-7528-16MST-8TX-4GSFP-HV-HV is a dual power input substation-grade managed Ethernet switch engineered for mission-critical energy and transport networks. It provides 16 ST fiber Fast Ethernet ports, 8 copper ports, and 4 Gigabit SFP uplinks for versatile high-performance networking.
Equipped with dual redundant 110/220 VDC/VAC power modules, this model maximizes availability in environments where power stability is essential. The dual-input design allows seamless failover, making it ideal for substation automation and other safety-critical applications.
Certified to IEC 61850-3 and IEEE 1613, the switch offers superior EMC immunity and withstands high levels of electrical interference without packet loss. Moxa’s Noise Guard ensures wire-speed reliability, while Turbo Ring and Turbo Chain deliver <20 ms recovery. Standard redundancy protocols, such as RSTP and MSTP, provide additional resiliency.
The integrated MMS server based on IEC 61850-90-4 supports direct SCADA integration, while Fibre Check continuously monitors optical link health. Industrial protocols, including Modbus TCP and EtherNet/IP, are supported, along with VLAN, QoS, and IGMP snooping for deterministic data delivery.
Comprehensive cybersecurity features include SNMPv3, IEEE 802.1X, RADIUS, TACACS+, SSH, and HTTPS. Proactive management is enabled through Syslog, RMON, LLDP, and event alarms via relay and email.
Housed in an IP40-rated aluminium chassis, the PT-7528-16MST-8TX-4GSFP-HV-HV operates reliably from -40 to 85°C, with fanless cooling and high vibration/shock tolerance.
With dual redundant HV inputs and fibre-centric design, this switch is the perfect fit for IEC 61850 networks requiring high-density fibre, Gigabit uplinks, and uncompromising reliability.
