The Moxa PT-7528-20MSC-4TX-4GSFP-WV is a fibre-centric managed Ethernet switch designed for IEC 61850-3 compliant substation and industrial networks. Featuring 4 copper Fast Ethernet ports, 20 multi-mode SC fibre ports, and 4 Gigabit SFP uplinks, this model provides superior long-distance connectivity and robust redundancy options.
Built to withstand harsh EMI and electrical noise, the PT-7528 complies with IEC 61850-3 and IEEE 1613 standards. Noise Guard technology ensures wire-speed zero packet loss, while the integrated MMS server allows seamless IEC 61850-90-4 SCADA integration for energy automation.
The switch delivers high availability with Turbo Ring and Turbo Chain (<20 ms failover), plus STP, RSTP, and MSTP support. Fibre Check continuously monitors link status, preventing downtime through proactive maintenance. Operators benefit from advanced features such as VLAN segmentation, QoS prioritisation, IGMP snooping, and port trunking.
Security is reinforced with IEEE 802.1X, TACACS+, RADIUS, SSH, and HTTPS, protecting critical infrastructure against unauthorised access. SNMPv3, RMON, and Syslog simplify centralised monitoring and diagnostics.
With dual 24/48 VDC inputs and an extended operating range of -40 to 85°C, the PT-7528-20MSC-4TX-4GSFP-WV is engineered for substation, utility, and rail applications requiring uncompromising performance and rugged reliability
