The PM-7200 Module Series includes Gigabit and Fast Ethernet modules for the PT Series rackmount Ethernet switches. IEEE 1588 interface modules provide hardware-based PTP functions for precise time synchronization across the network. Moxa's IEC 61850-3 Ethernet switches are designed specifically for substation environments.

The entire line of PowerTrans series has passed IEC 61850-3 and IEEE 1613 (conducted by KEMA) for GOOSE compliance and zero packet loss performance. The series also supports IEEE 1588 protocol for timing accuracy over substation LAN, which is highly favorable for large-scale distributed power grids.
