The IS220PSVOH1A is a high-performance Servo Pack module designed for the GE Mark VIe control system, specifically used for controlling electro-hydraulic servo valves in gas and steam turbine applications. This intelligent module ensures accurate positioning of actuators such as fuel valves, IGVs (Inlet Guide Vanes), and other servo-controlled mechanisms that are critical to turbine operation.

Functioning as part of the I/O network in the Mark VIe architecture, the IS220PSVOH1A receives command signals from the controller and adjusts hydraulic actuators accordingly, ensuring precise mechanical movement based on system requirements. It also includes embedded loop diagnostics, actuator position feedback, and signal conditioning to deliver reliable performance under dynamic load conditions.

Built with safety and reliability in mind, this module features dual redundant power supply inputs, self-diagnostics, and plug-and-play replacement, minimizing system downtime during maintenance. It interfaces seamlessly with GE’s ToolboxST software, enabling configuration, monitoring, and advanced troubleshooting.

The IS220PSVOH1A supports both simplex and TMR (Triple Modular Redundant) architectures and is capable of controlling one or two servo loops per module. Each loop includes pressure transducers, LVDT (Linear Variable Differential Transformer) feedback inputs, and internal reference generation for position calibration. This comprehensive design provides superior control accuracy, crucial for maintaining turbine efficiency and safety.

Used across a variety of turbine platforms, this servo module is built to withstand harsh environmental conditions, including high vibration and extreme temperature ranges. It plays a vital role in applications where performance, reliability, and tight control are non-negotiable.

Whether you’re upgrading or replacing components within a GE Mark VIe system, the IS220PSVOH1A ensures optimal servo control with reduced maintenance effort and increased system integrity.
