Product Overview
The GE IS220PSVOH1B is a servo interface I/O pack engineered for the Mark VIe control system. This industrial automation module acts as an electrical interface, linking one or two I/O Ethernet networks to a TSVO servo terminal board. It manages two servo valve position loops using the WSVO servo driver module. The front faceplate provides essential LED indications for quick status checks.

Applications
The IS220PSVOH1B is ideal for turbine control systems that require precise servo valve positioning. Typical applications include steam turbine inlet valve control, gas turbine fuel valve modulation, and other critical process control loops in power generation. Its robust design ensures reliable operation in demanding industrial environments.
Installation & Setup
After installation, configure the IS220PSVOH1B using the Control System Toolbox application. The module can be auto-reconfigured when replaced, a feature that you can enable or disable in the ToolboxST application's Component Editor. Alternatively, manual reconfiguration is possible via the Component Editor. If a terminal board is replaced, you must reconfigure the I/O pack manually. Use manual stroking, position ramping, or step current to test servo performance; the trend recorder will display any irregularities.
Maintenance & Reliability
Regularly inspect the front panel LEDs to monitor network and power status. The internal temperature sensor helps track thermal conditions, so verify that the module operates within specified ambient limits. Because the board includes flash memory and RAM, ensure firmware updates are performed carefully to avoid corruption. Periodic testing of servo loops is recommended to detect wear early and prevent downtime.
Compatibility & Integration
This module is designed for GE Mark VIe control systems. It connects to TSVO servo terminal boards and works with WSVO servo driver modules. The two I/O Ethernet networks (ENet1/ENet2) provide redundant communication paths, enhancing system reliability. Ensure your control system software supports the IS220PSVOH1B for seamless integration.
Selection Guide
Before purchasing, verify that the IS220PSVOH1B matches your Mark VIe system revision and that your existing TSVO terminal board is compatible. Confirm the required firmware version for your application. For genuine GE IS220PSVOH1B modules, PLC Source PRO offers quality assurance and reliable sourcing.
