The GE IS420ESWBH2A is an Industrial Ethernet Switch Module designed for the Speedtronic™ Mark VIe control system,
providing high-speed communication and network infrastructure for turbine and industrial automation applications.
1. Key Functions
Network Communication:
Acts as a managed Ethernet switch, enabling real-time data exchange between Mark VIe controllers, I/O modules, and HMI/SCADA systems.
Supports IEEE 802.3 (Ethernet) standards for reliable industrial networking.
Redundancy & Reliability:
Features dual power inputs (24V DC) for fail-safe operation in critical environments.
Supports Rapid Spanning Tree Protocol (RSTP) for network redundancy and fault tolerance.
Integration with Mark VIe Systems:
Seamlessly connects with ControlST software for configuration, monitoring, and diagnostics.
Used in triple modular redundant (TMR) and simplex control architectures for gas/steam turbine applications.
2. Technical Features
10/100 Mbps Ethernet ports for flexible device connectivity.
Industrial-grade design (operating temp: -40°C to +70°C) for harsh environments.
LED status indicators for port activity, power, and system health monitoring.
3. Applications
Power Generation: Facilitates communication in turbine control systems (e.g., GE 7FA, 9FA gas turbines).
Oil & Gas/Process Industries: Ensures robust data transfer in distributed control systems (DCS).
