The Moxa PT-7528-8MSC-16TX-4GSFP-HV is a high-voltage powered managed Ethernet switch optimised for IEC 61850-3 power substation networks and industrial automation. With 16 Fast Ethernet copper ports, 8 Fast Ethernet multi-mode SC fibre ports, and 4 Gigabit SFP uplinks, it offers versatile connectivity for large and distributed networks. Powered by a single 110/220 VDC/VAC input, this model integrates easily into substations and high-voltage facilities.
Engineered for demanding environments, the switch uses Moxa’s Noise Guard technology to eliminate packet loss under high EMI conditions. It features a built-in MMS server supporting IEC 61850-90-4 data modelling, streamlining SCADA integration and enabling secure, standards-compliant communication with intelligent electronic devices.
Redundancy is strengthened with Turbo Ring, Turbo Chain, and MSTP/RSTP/STP protocols, achieving recovery times of under 20 ms. Its comprehensive cybersecurity suite includes IEEE 802.1X, RADIUS, TACACS+, HTTPS, and SSH. Fibre Check delivers proactive diagnostics and fault detection on fibre links, while VLANs, quality of service, and IGMP snooping ensure predictable, prioritised traffic management.
Designed for wide-temperature operation (-40 to 85°C), the PT-7528-8MSC-16TX-4GSFP-HV is resilient against substation environments and industrial stresses. It is a trusted solution for utilities, railway control, and mission-critical infrastructure requiring reliable, high-port density switching with advanced redundancy and integrated cybersecurity.
