IS200TSVOH1B | Turbine Servo Valve Output Module

Key Features and Advantages

Precision Valve Control: The IS200TSVOH1B delivers high-accuracy ±10VDC or 4-20mA signals with 16-bit resolution, enabling precise positioning of servo valves in turbine control systems.

Multi-Channel Isolation: Four independently isolated output channels prevent ground loops and eliminate signal interference, allowing simultaneous control of multiple servo valves from a single module.

Fast Response: With 5ms update rate per channel, this module ensures rapid response to control system commands for critical turbine applications requiring dynamic valve adjustments.

Advanced Diagnostics: Continuous monitoring detects open-circuit conditions, short circuits, and output drift, providing early warning of potential valve control issues before they impact turbine operation.

Robust Industrial Design: Engineered for harsh environments, the IS200TSVOH1B features extended temperature operation (-40°C to +70°C) and high immunity to electromagnetic interference.
