SPASO11 ABB 14-Channel Analog Module 4-20mA/1-5V Specs

ABB SPASO11 Bailey INFI 90 Analog Output Module 14-Channel

Product Overview

The SPASO11 (SPASO11) is a high-precision 14-channel analog output module designed for the ABB Bailey INFI 90 and Network 90 Distributed Control Systems (DCS). This module serves as the critical interface between the control system logic and field-side final control elements. It is engineered to provide continuous, high-accuracy control signals required to drive proportional valves, actuators, positioners, and variable speed drives.

Operating within the modular INFI 90 rack environment, the SPASO11 (SPASO11) supports industry-standard 4–20 mA current loops and 1–5 VDC voltage outputs. Its high-density 14-channel configuration allows for significant space efficiency in complex industrial cabinets. The module is built for continuous operation in mission-critical sectors such as power generation, petrochemical refining, and water treatment, offering robust galvanic isolation to protect internal DCS logic from field-side electrical interference.
