Tableau de bornes servo General Electric IS200TSVOH1BDC

Description

The IS200TSVOH1BDC is a specialized servo termination board manufactured by General Electric as part of the Mark VI Speedtronic turbine control system series. This terminal board acts as the foundational structural interface layer linking external turbine instrumentation—such as electro-hydraulic servo valves and Linear Variable Differential Transformers (LVDTs)—to the main internal VME rack control cards. By establishing direct signal routing paths, the IS200TSVOH1BDC handles the clean transmission of valve current regulation demands, pulse rate flow signals, and critical LVDT feedback loops while minimizing single-point interface failures across automated steam or gas turbine systems.

Engineered to perform in demanding power generation environments, the IS200TSVOH1BDC features robust terminal blocks that accommodate stable, field-pluggable electrical wiring connections. The module coordinates with active servo processor boards to support real-time position tracking, sensor excitation control, and automated loop diagnostic synchronization under both simplex and Triple Modular Redundant (TMR) control architectures.

Features

• Dedicated Actuator Loop Termination: Expressly designed to provide secure termination points for multi-channel electro-hydraulic actuator servo control wiring.
• LVDT Instrumentation Support: Facilitates accurate signal mapping for high-frequency LVDT excitation outputs and position feedback tracing inputs.
• Pluggable Barrier Blocks: Outfitted with heavy-duty, barrier-type terminal block rows that maintain solid contact pressure and can be unplugged for fast component testing or replacement.
• Dual Architecture Configuration: Fully compatible with simplex configurations and fault-tolerant Triple Modular Redundant system layouts.
• Industrial Noise Suppression: Component orientation and path trace layouts are optimized to protect delicate analog instrumentation data from local electromagnetic interference.

Applications

• Mark VI Speedtronic steam and gas utility turbine control installations
• Field wiring termination for electro-hydraulic servo valve loop actuators
• Interface coupling for LVDT position feedback and pulse rate flow sensors

Installation Guidelines

• Field Terminal Connection: Secure the field instrumentation and actuator wiring leads into the matching pluggable barrier terminal slots on the IS200TSVOH1BDC card face. Tighten all screw contacts to industry standard specifications to guarantee continuity.
• Interconnecting Cable Routing: Utilize the specified multi-pin computer-grade ribbon cables with D-type connectors to bridge the IS200TSVOH1BDC board with its designated VME rack control counterpart.
• Electrostatic Discharge Mitigation: Ensure a verified electrostatic grounding strap is attached to the technician before executing any mounting, handling, or connection changes on the module.
