Description
General Electric (GE) IS220PSVOH1AThe
IS220PSVOH1A is a high-performance servo control module designed for GE’s Mark VIe and Mark VIeS turbine control systems. This module serves as a critical interface between Ethernet networks and servo terminal boards, enabling precise control of steam and gas turbines in industrial applications. Built with conformal coating and ruggedized components, it withstands harsh environments while ensuring reliable operation in mission-critical systems.
The IS220PSVOH1A acts as a bridge within GE’s Mark VIe architecture, managing communication between I/O networks and servo terminal boards. It supports dual servo loops for independent control of two servo valves, ensuring accurate positioning and response in turbine systems. Key features include:
- Dual Ethernet Connectivity: Two 10/100 Mbps ports for seamless integration with plant-wide networks.
- Real-Time Control: Processes analog and digital signals with sub-millisecond latency for dynamic turbine regulation.
- Diagnostic Capabilities: LED indicators for power, network status, and servo loop health, simplifying troubleshooting.
- Auto-Reconfiguration: Automatically adjusts settings when replaced, reducing downtime during maintenance.
- Extreme Environment Compatibility: Conformal coating and extended temperature range (-40°F to 158°F) make it suitable for petrochemical, power generation, and offshore applications.

- Power Generation (gas/steam turbines)
- Oil & Gas (refineries, offshore platforms)
- Chemical Processing
- Water/Wastewater Treatment
Case Study:
In a natural gas power plant, the IS220PSVOH1A controls a 50 MW gas turbine’s fuel injection system. Its dual servo loops maintain precise valve positioning during load changes, achieving 99.9% uptime and reducing maintenance intervals by 30% compared to legacy systems.
The IS220PSVOH1A outperforms similar modules in:
- Multi-Loop Control: Supports two independent servo loops, whereas many alternatives limit to one.
- Communication Flexibility: Built-in Ethernet and RS-485 interfaces eliminate the need for additional adapters.
- Environmental Resilience: Conformal coating and extended temperature range exceed industry standards for harsh environments.
IS220PSVOH1A
- Compatibility: Ensure alignment with GE Mark VIe systems and existing I/O networks.
- Environment: Choose the conformal-coated variant (catalog suffix “K”) for corrosive or dusty environments.
- Redundancy: Opt for hot-swappable configurations to minimize downtime in critical operations.
- Budget: Refurbished units offer cost savings without compromising performance.
- ESD Protection: Handle with anti-static gloves and storage bags to prevent damage.
- Firmware Updates: Regularly update firmware via GE’s Control System Toolbox to address security vulnerabilities.
- Mounting: Securely fasten the module to avoid vibrations in high-vibration environments.
- Power Supply: Use a filtered power source to prevent voltage spikes.
