- Mark VIe & Mark VIeS Control Systems
- Mark VI IS200 Series produced by General Electric
High-performance control processor module designed specifically for the Mark VIe distributed control system platform. Its primary functions are executing control logic, sequential management, and real-time data processing, making it suitable for industrial automation and power generation applications. As the central processing unit in the control architecture, the module coordinates communication between I/O modules, field devices, and monitoring systems to ensure stable and deterministic system operation.
It can handle critical tasks such as signal processing, alarm management, system diagnostics, and fault handling, while maintaining synchronized operation among distributed controllers. Its industrial-grade design allows it to be deployed in demanding environments such as turbines, power plants, and process control facilities where real-time performance and system integrity requirements are extremely high.
The IS420ESWBH2A GENERAL ELECTRIC Industrial Ethernet Switch may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
This module receives analog and/or digital input signals from connected sensors or subsystems, performs signal isolation, filtering, and level conversion via onboard circuitry, and then transmits the processed data to the central controller via a high-speed backplane or internal communication bus. Simultaneously, it parses control commands from the main processor and distributes corresponding output signals to relevant field devices or subordinate modules. All of this is achieved through coordinated data exchange, electrical isolation, and embedded firmware logic.
The IS420ESWBH2A is an unmanaged switch requiring no software configuration, but specifically designed to meet the time-sensitive needs of IONet (Industrial Operations Network):
1. Real-time Data: Designed to process multicast and broadcast packet streams with minimal latency, ensuring timing consistency of data within the control system.
2. Visual Indicators: Equipped with dedicated LED indicators to display power status and port status (link status, activity status, duplex status, and speed).
3. Maintenance Notes: If the switch experiences a voltage drop (voltage not dropping to 0V), the LED indicators may stop flashing or scrolling, requiring a manual restart to restore normal operation.
1. Power Generation: Widely used in gas turbine and steam turbine control systems to manage real-time protection, automation, and diagnostic data between controllers and I/O components.
2. Oil & Gas: Used for distributed control in refineries and petrochemical plants where networks must withstand harsh environmental conditions.
3. Modern Infrastructure: Deployed in the metallurgical, mining, water treatment, and paper industries to provide highly available networks for complex automated processes.
4. SIL Certified Systems: Supports safety-critical applications compliant with IEC 61508 standards to protect personnel and property.
