1. Product Description
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.
