Product Description
GE IS210WSVOH1A | WSVO Servo Driver Heatsink Assembly for Mark VI/VIe Turbine Control
Dual-Channel Servo Valve Control & LVDT Signal Processing for Precision Turbine Actuation
1. Product Overview

The GE IS210WSVOH1A is a critical WSVO (Servo Valve Output) heatsink assembly designed for GE Mark VI/VIe turbine control systems, specifically engineered for gas turbine and steam turbine servo actuation control. As a high-performance servo driver board with integrated heatsink, it combines dual-channel servo valve output (±10V DC / 4-20mA) and LVDT (Linear Variable Differential Transformer) position feedback signal processing to enable precise control of turbine fuel valves, guide vanes, and steam admission valves. The assembly integrates IS210WSVOH1A servo driver PCB (conformal coating for environmental protection) and a heavy-duty aluminum heatsink, ensuring efficient heat dissipation for continuous operation in high-temperature industrial environments (0°C to +60°C). It supports 28V DC power input, 2.5kV AC signal isolation between channels and ground, and seamless integration with Mark VI/VIe controllers via IS200TSVCH1A servo terminal boards, providing real-time position feedback and closed-loop control for turbine actuation systems. Equipped with built-in overcurrent/overvoltage protection, thermal shutdown, and self-diagnostic functions, the IS210WSVOH1A ensures reliable performance in critical turbine control applications, making it ideal for power generation, oil & gas, and industrial turbine operations requiring high-precision actuation control and system availability.

4. Installation & Maintenance
Installation: Mount on Mark VI/VIe backplane with IS200TSVCH1A terminal board; connect 28V DC power, servo valve outputs, and LVDT feedback inputs. Configure output signal type (voltage/current) via hardware jumpers; verify signal isolation and heatsink mounting for thermal efficiency.
Maintenance: Inspect heatsink for dust accumulation quarterly; clean with compressed air if necessary. Monitor output current/voltage and temperature via controller diagnostics. Check terminal connections for tightness and corrosion; replace conformal-coated PCB if damaged by moisture or chemical exposure.

Fault Diagnosis: Retrieve fault codes via Mark VI/VIe HMI (overcurrent, overvoltage, thermal shutdown). Verify LVDT feedback signal integrity with a multimeter; check servo output voltage/current for consistency with controller setpoints. Inspect heatsink thermal paste for degradation if overheating occurs.
