GE IS200VROCH1BBR Control Board

Product Introduction

The GE IS200VROCH1BBR Control Board is a high-performance module designed for the GE Mark VIe distributed control system. It functions as a vital interface between turbine control logic and field devices, managing real-time operations, executing control algorithms, and ensuring reliable communication with other system components. Engineered with robust isolation, noise immunity, and extended temperature tolerance, the IS200VROCH1BBR is well-suited for demanding industrial environments such as gas, steam, and combined-cycle power plants. Its architecture supports deterministic control cycles, redundant system topologies, and continuous monitoring for critical process applications.

Product Specifications

Applications

The IS200VROCH1BBR is widely deployed in:

• Gas and steam turbine control systems requiring high-speed response

• Power plant distributed control systems (DCS) and balance-of-plant operations

• Real-time process automation in petrochemical and industrial facilities

• Redundant control networks where deterministic data exchange is critical

• Integration with GE Mark VIe controllers for generator protection and load-shedding logic

Advantages

• Deterministic Performance: Guarantees consistent real-time control cycles under heavy loads.

• Robust Isolation: High isolation voltage prevents cross-channel interference and protects sensitive electronics.

• Flexible Communication: Supports Ethernet and RS-485 as well as native Mark VIe backplane communication.

• Industrial Durability: Rated for extreme temperatures, vibration, and electrical noise common in turbine halls.

• Redundant Operation: Fully compatible with dual and triple-modular-redundancy Mark VIe topologies.

• Ease of Maintenance: Modular design with clearly labeled connectors and built-in diagnostics simplifies service.
