GE IS200VCRCH1B Product Specification
Product Overview
The GE IS200VCRCH1B is a high-reliability control relay module engineered for GE’s Mark VIe Turbine Control System, a cornerstone of industrial automation in power generation and heavy machinery applications. As a critical component of the Speedtronic family, this module serves as a dynamic interface between the control system and field devices, enabling precise relay control for turbine protection and speed regulation. The GE IS200VCRCH1B integrates advanced signal processing with rugged design, making it essential for industries requiring fail-safe operation, such as power plants, oil and gas facilities, and manufacturing complexes.
Designed to manage up to 16 relay outputs, the GE IS200VCRCH1B processes analog and digital signals from the turbine control system to execute critical commands, such as emergency shutdowns or speed adjustments. It supports 24 VDC power input and features optical isolation for each channel, ensuring immunity to electromagnetic interference (EMI) in harsh industrial environments. The module’s compact form factor (228.6 mm × 127 mm × 101.6 mm) and 1.5 kg weight facilitate easy integration into control cabinets, while its hot-swappable design allows maintenance without system downtime.
In automation architectures, the GE IS200VCRCH1B acts as a safety-critical hub, translating control signals from the Mark VIe CPU into physical relay actions. Its built-in diagnostics monitor relay health and signal integrity, reducing mean time to repair (MTTR) and enhancing system availability. By combining hardware durability with software configurability, the module empowers engineers to optimize turbine performance, ensure regulatory compliance, and minimize operational risks in mission-critical applications.

Main Features and Advantages
Redundant Relay Configuration: The GE IS200VCRCH1B supports 16 independent relay channels, each with SPDT contacts rated for 2A at 24 VDC, enabling simultaneous control of multiple actuators or safety circuits. This redundancy ensures fail-safe operation in critical scenarios like turbine emergency shutdowns.
Optical Isolation Technology: Each channel features optical isolation, protecting the module from voltage spikes and EMI, the GE IS200VCRCH1B maintains signal integrity in high-noise environments typical of power plants or manufacturing floors.
Hot-Swap Capability: The module’s hot-swappable design allows replacement without powering down the Mark VIe system, minimizing downtime during maintenance. This feature is vital for 24/7 operations where system availability is non-negotiable.
Real-Time Diagnostics: Built-in LED indicators and serial communication (RS-485) provide real-time status updates on relay health, contact wear, and power supply stability. Engineers can access diagnostic data via the Mark VIe HMI, enabling proactive maintenance.
Modular System Integration: As part of GE’s Mark VIe ecosystem, the GE IS200VCRCH1B integrates seamlessly with other modules (e.g., CPU, I/O cards), forming a cohesive control solution. This modularity allows for easy system expansion or retrofitting in existing installations.
