The GE IS420ESWBH2AAX is a 16-port IONet switch for the GE Mark VIe control system. It features two multi-mode fiber optic ports and is certified for use in hazardous locations (HazLoc). This switch is designed for applications in explosive environments that require a high port count and reliable, long-distance communication.
Key Features and Applications
This switch combines a high-density port count with the robust safety and communication features needed for critical industrial networks.
- 16-Port IONet Switch: The high number of ports makes this switch an ideal central hub for complex control systems with extensive I/O (Input/Output) requirements. It can connect a large number of devices to the main controller, simplifying network architecture and reducing the need for multiple switches.
- Dual Multi-Mode Fiber Ports: The two multi-mode fiber optic ports are a key feature for industrial environments. Fiber optic cables are immune to electromagnetic interference (EMI), a common problem in power plants and industrial facilities. The two ports can be configured in a redundant ring, where data can travel in both directions. If a fiber cable is cut, communication is maintained via the alternate path, ensuring uninterrupted operation. Multi-mode fiber is suitable for communication over distances up to a few kilometers.
- Hazardous Location (HazLoc) Certification: The “AX” at the end of the part number is a critical safety designation. It indicates that the switch has been designed and tested to meet strict safety standards, ensuring it will not produce sparks or excessive heat that could ignite flammable gases, vapors, or dust. This is essential for safety and regulatory compliance in high-risk areas.
The GE IS420ESWBH2AAX is a vital component in mission-critical applications such as:
- Oil & Gas: Used on offshore platforms, refineries, and pipelines to provide safe and reliable network communication in areas with explosive atmospheres.
- Chemical Plants: Employed in facilities that process flammable or volatile chemicals, where safety and operational continuity are paramount.
- Power Generation: Installed in areas that may have a risk of gas leaks or combustible dust, ensuring the control system remains safe and functional.
