GE IS420ESWAH4A ESW Series E-Switch (8-port, 1 SM Fiber)

GE IS420ESWAH4A ESW Series E-Switch (8-port, 1 SM Fiber)

  • System Redundancy: In critical applications, these switches can be deployed in redundant pairs. This configuration ensures that if one switch fails, the other can take over seamlessly, preventing communication loss and maintaining continuous control of the system.

The GE IS420ESWAH4A is commonly used in:

  • Power Generation: To link turbine and generator control modules to the main processor, particularly when control panels are located far from the equipment they manage.
  • Oil & Gas: For connecting I/O modules in remote or hazardous areas where long-distance fiber optic communication is necessary.
  • Industrial Plants: In large-scale process control systems where reliable, high-speed communication is required over long distances.

الوصف

The GE IS420ESWAH4A is an 8-port E-Switch from the ESW Series of the Mark VIe control system. Its key feature is the inclusion of one single-mode (SM) fiber optic port, which is designed for long-distance communication. This switch is crucial for providing reliable, high-speed data transfer between the main controller and I/O modules, especially in large-scale industrial plants.

 

Key Features and Applications

 

The IS420ESWAH4A is engineered for high-performance networking in demanding industrial environments.

    • 8-Port E-Switch: The switch serves as a data hub, managing the flow of information between various devices connected to it. With 8 ports, it can support a significant number of I/O modules, enabling the system to collect a large amount of data from and send commands to field devices.
    • Single-Mode Fiber Port: The single-mode fiber optic port is the distinguishing feature of this model. Unlike multi-mode fiber, single-mode fiber is optimized for transmitting data over very long distances, often several kilometers.

This makes it ideal for connecting control panels to remote equipment or other control rooms without data degradation from EMI (electromagnetic interference) or signal loss over distance.

  • IONet Protocol: The switch operates on the IONet protocol, a proprietary GE network designed for real-time, low-latency control. This ensures that critical data is delivered quickly and reliably, which is vital for the fast response times required in turbine and generator control.
  • System Redundancy: In critical applications, these switches can be deployed in redundant pairs. This configuration ensures that if one switch fails, the other can take over seamlessly, preventing communication loss and maintaining continuous control of the system.
