RELY-SV-PCIe

Sampled Value Subscriber DAN PCIe NIC

RELY-SV-PCIe card is a smart pluggable board that comprises in the same device hardware and software resources to implement intensive processing, specialized networking, synchronization and security oriented services for Smart Grids based on IEC 61850 standard.

The device uses dedicated hardware for Layer 2 IEC 61850-9-2 Sampled Value frame processing and converts any conventional computer in a powerful tool for IEC 61850 analysis, through a standard PCI Express interface.

It can be used as a multi-media PCIe DAN, operating as an HSR/PRP node of a high-availability network or connecting to a Conventional Ethernet network. Additionally, RELY-SV-PCIe implements high accuracy clock synchronization based on IEEE 1588 standard.

These key features make RELY-SV-PCIe platform the most reliable and multipurpose device for critical environments.
