RELY-TSN-CPPS 2020-09-25T10:47:48+02:00


Time-Sensitive Networking Gateway

Time-Sensitive Networking (TSN) allows to merge OT and IT worlds and guarantees the interoperability and standardization of all the devices in a deterministic Ethernet network.

This technology offers a significant cost reduction in equipment investment, maintenance, seamless integration of advanced analysis services and a reduction of dependence on a single vendor.

All the above advantages make Time-Sensitive Networking the reference technology in the Ethernet networks of the future.

RELY-TSN-CPPS is Relyum’s first TSN gateway designed for seamless implementation of Deterministic Ethernet networks. Based on SoC-e*’s TSN technology, this device benefits from a robust and field proven design used in the most demanding sectors (railway, aerospace, automotive, industrial automation, etc.).

RELY-TSN-CPPS includes 2 multi-media Gigabit external ports that allow to connect to the TSN network, through redundant links based on IEEE 802.1CB standard.

On the other side, RELY-TSN-CPPS simplifies connectivity in the Edge by implementing a flexible multi-vendor input switchboard to support communication with OT devices. Also, direct connection with digital and analogue sensors can be added to the platform.

These key features make RELY-TSN-CPPS the most reliable and multipurpose networking device for critical environments.
