RELY-TSN4 — 4-port 1G TSN switch
A four-port switch supporting the TSN standards. It is used in demanding sectors such as railway, aerospace, automotive and industrial automation.



Overview
TSN combines critical and best-effort traffic on one deterministic Ethernet network, reducing equipment and maintenance costs and dependence on a single vendor. RELY-TSN4 was RelyUm's first TSN switch. Being FPGA-based, it can follow updates to the TSN standards.

Frequently asked questions
Where is it used?
When you want to combine deterministic control traffic and general traffic on one network. It is used in railway, aerospace, automotive and industrial automation.
How does it differ from RELY-TSN12?
They differ in the number of ports. Choose based on whether four ports are enough. Please contact us to discuss the configuration.
What happens when the TSN standards are updated?
Being FPGA-based, it can be updated for new profiles. We can advise on timing case by case.
What about price and lead time?
These depend on the configuration. Tell us what you are considering.
