    Overview
       
    JetNet 3508 is 8-port Plug-n-Play Unmanaged Redundant Ethernet Switch, specially designed for industrial applications. JetNet 3508 supports plug-n-play Redundant Super Ring. JetNet 3508 has also redundant DC power inputs for power redundancy. The relay output for failure alarm enhances real-time system management. To meet the requirement of your harsh environment, JetNet 3508 uses a robust aluminum case, offering IP31 standard protection.

    Super Ring-Recovery time < 300ms
    One of the main topics in Industrial Automation field is to ensure your system will run non-stop. A minor failure in the communication process may cause the whole system to break down. As a result, you might suffer from substantial damage in terms of extra time and monetary losses. JetNet 3500 Series Switches are your ultimate solution. With Super Ring (Self-healing Redundant) technology, JetNet 3500 provides you with a self-recovery mechanism. If any segment of your primary communication path is broken or disconnected, Super Ring technology allows JetNet 3500 to self-reconfigure and to provide a redundant path in the network. With its ultra fast recovery time, which is less than 300ms, your mission-critical applications are protected from any network interruptions or temporary malfunctions. With the recovery time that fast, you won't even notice a network failure.

    Alarm Relay Output
    JetNet 3500 has a built-in relay contact. You can use this relay contact to set up your warning system based on your requirements. The relay output function will form a short circuit when power fails or port link breaks, and will automatically form an open circuit when port link or power input resumes. JetNet 3500 uses the relay output to trigger your warning system, and inform your maintenance engineers of the problems, allowing you to react promptly to the errors and adjust accordingly in the shortest time.
