Multilin Adds Redundancy Protocols to its 350 and F650 Protection Relays

GE is excited to announce the availability of its enhanced Multilin™ 350 and F650 protection relays, now supporting seamless redundancy protocols (IEC 62439) including Parallel Redundancy Protocol (PRP), and High-availability Seamless Redundancy (HSR). These additions increase network availability and reliability with zero recovery time in the event of communications failures for critical applications. The inclusion of IEEE 1588 (Precise Timing Protocol) provides the benefit of accurate Ethernet-based time synchronization.

The addition of Synchrocheck functionality (350) and internal RTD board (339) provides the ability to meet application specification requirements and allows customers to use the Multilin 350 in incoming feeders and 339 for cost-effective motor protection applications. The latest feature enhancements now available in the Multilin F650 include improved and updated implementation of the IEC 61850 standard aligned with Edition 2 and Rapid Spanning Tree Protocol (RSTP) providing advanced communications for industrial and utility applications. Perfect for Industrial and utility applications, these cost-effective  protection and control devices are used to perform primary or back-up circuit protection and control on a wide variety of applications.
