ABB SPASO11 Symphony Plus Analog Output Module

ABB SPASO11 Symphony Plus Analog Output Module is a 14‑channel analog output slave for the Symphony Plus S+ HR Harmony Rack I/O system, translating PLC control commands into precise analog field outputs. Its 14 channels can deliver either 4–20 mA current outputs or 1–5 V voltage outputs to drive actuators, valves, and other analog field devices in process automation. Designed for use within the Harmony Rack I/O family, SPASO11 is compatible with legacy Infi 90/ Bailey systems, enabling migration paths and mixed installations within traditional ABB control architectures. As a dedicated analog output module, it provides scalable, channel‑level control within distributed automation environments.
