As an official UK distributor of Moxa products since 2014, we at Impulse are proud to be affiliated with Moxa Technical College. Our partnership enables us to provide comprehensive in-house training and first-line technical support, and our team of Industrial Internet of Things (IIoT) specialists are fully equipped to guide you through every step of the process. Whether you require assistance with installation, troubleshooting or anything else, our team is ready to assist you.
Technical Support from Impulse
Our commitment doesn't end with the initial setup—we provide lifelong technical support for the entire range of Moxa products at no extra charge. Count on us to ensure that your network operates at its peak performance throughout its entire lifespan.
The Moxa PT-7528 Series is a family of IEC 61850-3 compliant Layer 2 managed rackmount Ethernet switches designed for mission-critical power substation and industrial automation networks. With a modular design supporting up to 28 Fast Ethernet copper or fibre ports and up to 4 Gigabit SFP uplinks, these switches provide the flexibility needed for complex, high-density infrastructures. Built-in MMS server support based on IEC 61850-90-4 enables seamless integration with SCADA systems, while Moxa’s Noise Guard™ technology ensures zero packet loss at wire speed even under severe electromagnetic interference.
The PT-7528 Series enhances reliability with multiple redundancy technologies, including Turbo Ring, Turbo Chain, STP/RSTP, and MSTP, delivering network recovery in less than 20 ms. Wide redundant power inputs covering 24/48 VDC or 110/220 VDC/VAC ensure continuous operation, even during supply failures. Extended operating temperature support from -40 to 85°C makes the switches suitable for extreme outdoor and substation environments.
Security and management features include RADIUS, TACACS+, IEEE 802.1X, HTTPS, and SSH for access control, while IGMP snooping, VLAN, and quality of service keep traffic predictable and efficient. Fibre Check™ provides proactive monitoring and diagnostics for fibre links, and bandwidth management prevents network congestion. Designed for long-term reliability, the PT-7528 Series is ideal for substation automation, power grid communications, and other demanding industrial applications requiring maximum uptime and robust cybersecurity.
