Product Description

The SPAS011 is a high-density analog output (AO) module designed for ABB Symphony Plus and Harmony Rack systems. It converts digital control signals into precise analog outputs to drive final control elements such as valve positioners, variable speed drives, and industrial actuators.

Featuring 15 independent channels, the SPAS011 ensures high-fidelity signal transmission with minimal drift. Its galvanically isolated architecture protects the control logic from field-side electrical noise, making it suitable for mission-critical industrial environments. The module integrates onboard diagnostics for loop verification, ensuring reliable long-term operation.

FAQ

Does the SPAS011 support 4–20 mA control loops?
Yes, it is primarily used for standard 4–20 mA industrial actuator and valve control.

How does it behave during a controller communication loss?
Outputs can be configured to hold their last value or transition to a pre-defined safe state (e.g., 4 mA or 0 mA) to prevent process damage.

What advantages does SPAS011 have over legacy AO modules?

  • Higher channel density: 15 channels vs. 8 channels in older models.

  • Enhanced diagnostics: Loop-back testing to verify output accuracy.

  • Improved integration: Direct compatibility with modern Harmony/S+ systems.
