Network equipment for industryIndustrial switching hub TW900 type
This type conforms the standards of 19-inch rack and 1U size. This is an industrial switching hub with port configuration which is needed in the market where high reliability and environmental resistance are called for.
Product Features
This model is equipped with a 24-port gigabit interface with high environmental resistance and reliability. A flexible gigabit network can be configured with duplication of line through loop configuration. Parts with long operational life are used for the electrolytic capacitor. Because it is a fan-less type, no maintenance parts are required. The data transmission chennnel can be reconstructed within 0.5 seconds when failure occurs. In so doing, the system availability and and reliability are greatly improved. In addition, this model comes with a noise filter having 2 kV of power source noise tolerance. Further , by the high withstand voltage (AC2000 V/ 1 minute) of the power supply module, it can be used under high temperature, noise and high voltage.
- 2 ports of SFP slot are available.
- It offers the redundancy by loop configuration
- Intelligent function
- No maintenance parts are required because of fan-less design.
- This model can be used under high temperature, noise and high voltage.
- It comes with Meiden's unique the Real-Time Transport Protocol (RTP) function and high speed spanning tree protocol
- Japanese Power Utility Standard (on Protection Relay) B-402 Compliant
