With IEC 61850-3 and IEEE 1613 certifications, modular design, and high copper port density, the PT-7528 is the best fit for station-level deployments in power substations.
The PT-7528 series is a 28-port modular managed rackmount switch with 24 fixed 10/100BaseT(X) RJ45 copper ports. To offer higher deployment flexibility, the PT-7528 works with PM-7500 series modules, which allow users to add up to 4 fiber ports that are dedicated to upstream or backbone connectivity, and are popular deployment for bay-level communication. In addition, IEC 61850-3 and IEEE 1613 standards compliance combine with advanced Layer 3 management, giving the PT-7528 the environmental endurance and network capabilities needed to excel in power substation applications.
"The PT-7528 is the best value product among its peers because it specializes in meeting the most common substation network requirements. Modular designs are very useful when flexibility is needed, but there will always be certain scenarios that most frequently encountered. In IEC 61850-3 power substations, the most popular deployment requirement in station level connectivity includes 24 10/100BaseT(X) RJ45 ports, and 4 fiber ports. In the past, customers could use our modular-design PT-7728 series with 4 modular slots for up to 4 Gigabit ports and 24 Fast Ethernet ports." said Larry Wang, product manager at Moxa. "The new PT-7528 switch reduces the overall product cost by using fixed slots to deliver the same 24 Fast Ethernet ports, and retains some modularity with a slot for up to 4 fiber ports."
