The IS420ESWBH1A REV B is a high-performance Ethernet IONet Switch from GE, specifically designed for use within the GE Mark VIe control platform. It enables seamless and reliable communication between control system components, including I/O modules, controllers, and operator interfaces. This industrial-grade switch plays a vital role in maintaining efficient data transfer across turbine and plant automation networks.

This managed switch comes with 8 standard 10/100Base-TX ports and 4 optional fiber ports, ensuring flexible connectivity for various network topologies. It is ideal for demanding applications where network reliability, speed, and fault tolerance are critical. The IS420ESWBH1A supports both star and ring topologies, offering robust redundancy and network fault recovery capabilities.

Built for harsh industrial environments, the switch operates within a wide temperature range and resists vibration and electrical noise, which makes it ideal for power plants and heavy industrial applications. Its rugged metal enclosure and DIN-rail mounting design allow for compact installation within control cabinets and panels.

As part of the GE Mark VIe system, the IS420ESWBH1A is pre-engineered for compatibility with GE’s IONet protocol, which ensures deterministic data flow and time-sensitive control communication. The switch helps minimize latency, maintain system synchronization, and improve the overall responsiveness of turbine controls.

The IS420ESWBH1A REV B includes built-in diagnostics and monitoring capabilities, allowing for real-time health checks and troubleshooting of network issues. It also supports features such as Quality of Service (QoS), VLANs, and port mirroring, helping system engineers manage traffic efficiently and securely.

With its plug-and-play configuration and compatibility with GE ControlST software, integration into existing GE Mark VIe architectures is simple and efficient. This reduces commissioning time and supports long-term system scalability and maintenance.
