The MDS-G4028 is the standard temperature variant of Moxa’s modular 28-port platform. Certified to IEC 61850-3 and IEEE 1613, it is built for high-availability substation and industrial Ethernet.
It provides a mix of embedded Gigabit ports and LM-7000H expansion slots, supporting copper, fibre, and PoE+ modules. Dual hot-swappable LV (24/48 VDC) or HV (110/220 VAC/VDC) power modules provide redundant supply resilience.
With PRP/HSR redundancy, Turbo Ring/Chain, RSTP, MSTP, IEEE 1588 PTP, MMS/IEC 61850-90-4, and an HTML5 interface, it combines scalability with advanced time synchronisation and SCADA integration. Operating from -10 to 60°C, it is ideal for large-scale substation networks.

Wireless Solution Saves Time and Reduces Overheads for OT Machinery Monitoring Project
Our customer was looking for ways to improve efficiency and reliability, and reduce operation costs and overheads for their manufacturing facility. The initial step in this transformation was to add additional monitoring and measurements to several areas of their facility to allow the collection of usage data from older machinery for analysis. The machinery to be analysed would be located in many areas of the complex, with some sitting in concrete outbuildings far from the source of the main network.
