Industrial 5-Port Web-Managed Ethernet Switch Redundant Ethernet Super Ring Supports VLAN/QoS/IGMP Snooping Web-based Configuration Redundant DC Power Inputs Alarm Relay Output Robust Aluminum case, IP31 DIN-Rail/Wall-mounting/Desktop Installation

JetNet 4005 is a 5-port Web-Managed Industrial Ethernet Switch, which is specially designed for industrial applications. JetNet4005 comes with Super Ring technology, which is used to set up a redundant Ethernet ring topology. JetNet 4005 also has redundant DC power inputs that can be connected to DC power sources simultaneously. JetNet 4005 is equipped with a terminal block and a DC adapter jack for power input. JetNet 4005 uses a robust aluminum case that meets IP31 standard. JetNet 4005 provides port-based VLAN, which allows each port to create a single VLAN and overlap the other ports. The RJ-45 ports support auto MDI/MDI-X function. This function can auto detects whether a cable is a crossover or straight one. JetNet 4005 fulfills the requirements of industrial automation.

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. JetNet4000 Series Switches are your ultimate solution. With Super Ring (Self-healing Redundant) technology, JetNet 4000 provides you with a self-recovery mechanism. If any segment of your primary communication path is broken or disconnected, Super Ring technology allows JetNet 4000 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 networkfailure. Super Ring technology provides you a reliable network. With the self-healing and redundant capabilities, youcan be assured that your automation system will operate nonstop.

QoS - Determinism Ethernet Technology
The primary concern about utilizing Ethernet technology in the arena of industrial automation is that Ethernet is not deterministic. Unlike other traditional field bus, Ethernet uses the collision domain (CSMA/CD) technology to determine the sequence of data transmission, which is not ideal for applications that require real-time responses. Quality of Service (QoS) is implemented to improve Ethernet's shortcoming on determinism. It provides the ability to prioritize data packets according to their importance to the system. In a typical scenario, various data packets might be queued in a switch at the same time. JetNet 4000 with QoS function can detect information of each packet to determine which ones are top priority tasks. Ethernet packets, such as control messages, will be dealt with first, and then low priority packets, such as collected data. Korenix JetNet 4000 Series such as collected data follows with QoS function helps determine traffic flow and data transmission. JetNet 4000 Series is specially designed and ideal for real-time applications.
