The ABB SPASO11 (also known as ASO11) is an Analog Output module that delivers 14 independent channels. Each channel supports standard process output signals with high resolution and isolation for noise immunity. It integrates seamlessly into Symphony Plus HR Series racks and maintains backward compatibility with Harmony / INFI 90 systems. The module is optimized for closed-loop control applications requiring reliable, repeatable analog outputs.

• 14 Independent Channels: High-density analog outputs for efficient I/O utilization.

• Standard Signal Support: 4-20 mA and 1-5 V outputs per channel.

• High Accuracy: Precise signal conversion with excellent linearity and repeatability.

• Robust Isolation: Channel-to-channel and channel-to-power isolation for superior noise immunity.

• Hot-Swappable: Supports online replacement in compatible rack configurations.

• Modular Harmony Rack Design: Easy integration and scalability within Symphony Plus systems.

• Backward Compatibility: Form-fit-function with legacy INFI 90 / Harmony installations.

• Diagnostic Features: Built-in status monitoring for improved system reliability.
