The IS200TRLYS1B is a Relay Output Terminal Board manufactured by General Electric, designed specifically for the Mark VI Speedtronic series of gas and steam turbine control systems. It functions as a critical interface between the Mark VI control system and external field devices, providing reliable relay-based output signal termination and switching for discrete control applications. The board features 12 Form C (changeover) magnetic relays with integrated coil diagnostics, enabling precise and secure control of industrial actuators, valves, motors, and alarms. It supports seamless integration with VME-based Mark VI systems, operating in simplex, dual-redundancy, and triple-redundancy (TMR) configurations to ensure operational integrity in harsh industrial environments.

The IS200TSVOH2B is a dedicated servo valve interface terminal board designed by General Electric for Mark VIe Speedtronic turbine control systems. It serves as the critical interface between the control system and electro-hydraulic servo valves, managing up to six Linear Variable Differential Transformer (LVDT) valve position inputs and two servo valve outputs. The board enables precise control of steam and fuel valves in gas and steam turbines, ensuring accurate position feedback and reliable actuation for optimal turbine performance and safety. It integrates seamlessly with Mark VIe controllers, providing robust signal processing, noise immunity, and simplified wiring for industrial turbine applications.

The IS200TVBAH2AAA is a specialized vibration input terminal board engineered by General Electric for the Mark VI Speedtronic turbine control system. It serves as a dedicated interface for connecting vibration and position sensors to Mark VI controllers, enabling real-time monitoring of critical mechanical parameters in industrial turbomachinery. The board supports up to 14 sensor connections, including seismic velocity probes, accelerometers, Proximitors, and position sensors, with integrated signal conditioning and EMI protection to ensure data accuracy in harsh industrial environments. It operates on 28 VDC power and is compatible with both simplex and triple modular redundant (TMR) system architectures, providing flexible deployment across diverse turbine control applications. Its modular design facilitates easy integration with Mark VI I/O packs and ToolboxST software for configuration, calibration, and diagnostics, making it an essential component for predictive maintenance and machinery protection.
