IEC 61850 Ethernet switch with MMS servers
The new PowerTrans PT-7528 series Etherent switch from Moxa is believed to be industry’s first Ethernet switch designed to fulfill IEC 61850-90-4 requirements and is also equipped with built-in MMS servers.
The switches are designed for power substation automation applications in extremely harsh environments. Taking advantage of Moxa’s Noise Guard technology, the PT-7528 series is compliant with IEC 61850 standards, and has an EMC immunity that exceeds IEEE 1613 Class 2 standards to ensure zero packet loss while transmitting at wire speed.
The PT-7528 series also features critical packet prioritization (GOOSE, SMVs, and PTP), a built-in MMS server, and a configuration wizard designed specifically for substation automation. With Gigabit Ethernet, redundant ring, and 110/220 VDC/VAC isolated redundant power supplies,
A wide range of switch options are available to provide multi-type port configurations. The modular design of the units also also makes network planning easy, says the company, and enables greater flexibility by letting users install up to four modular fibre ports and 24 fixed 10/100BaseT(X) RJ45 ports. In addition, the switches offer the fiber digital diagnostic monitoring (DDM) function for ST, SC, or SFP. Along with the optional front or rear wiring, these features together make the PT-7528 suitable for a variety of industrial applications.
Support for IEC 61850-90-4 data modeling allows these Ethernet switches to be controlled, monitored, and managed via a power SCADA system, which is critical for reliable electrical substation operation and eliminates the need for any additional network management software.
