IS220PSVOH1B | Power Supply Voltage Output Module

Key Features and Advantages

Precision Voltage Output: The IS220PSVOH1B delivers highly accurate voltage signals with ±0.1% accuracy and 16-bit resolution, enabling precise control of actuators and positioners in turbine systems.

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

Flexible Configuration: Software-selectable output ranges (0-10V or ±10V) adapt to various field devices without hardware modifications, simplifying system integration.

Advanced Diagnostics: Continuous monitoring detects open-circuit conditions, short circuits, and out-of-range operation, providing early warning of field wiring issues before they impact turbine control.

Robust Industrial Design: With extended temperature operation (-40°C to +70°C) and high immunity to electromagnetic interference, the IS220PSVOH1B performs reliably in harsh turbine environments.
