Overview

Carat10-D6TX2SC20D3-HV DIN-Rail unmanaged industrial Ethernet switch is a switch compliant with rail transit applications, specially designed for network communications in rail transit, industrial automation, and other fields. It complies with EN50121 industry standard, and has obtained CE, FCC, and other certifications. It is suitable for use in harsh working environments, providing highly reliable industrial network connection solutions for different industrial application sites.

Carat10-D6TX2SC20D3-HV adopts store-and-forward switching mode, providing 2x 100M SC fiber ports and 6x 10/100Base-TX RJ45 ports.

Carat10-D6TX2SC20D3-HV features a high-strength corrugated metal housing structure that can shield electromagnetic interference and resist vibration and shock. The industrial fanless design avoids and reduces failure points caused by fan stoppage. Additionally, when a power failure occurs, the built-in relay alarm function can alert network administrators, ensuring long-term stable, reliable, and safe operation of the product in various harsh industrial environments.
