ABB DAO01 Analog Output Module Freelance Advant OCS

Product Overview

The ABB DAO01 is a high-precision analog output module designed for the ABB Bailey, H&B Freelance, and Advant OCS control system families. This module serves as a critical bridge between the digital control logic of the DCS and physical field equipment, converting internal digital signals into standardized analog current or voltage signals.

The DAO01 provides 16 independent channels, allowing for the simultaneous control of multiple actuators, variable speed drives (VFDs), and control valves. It is engineered for deterministic performance in demanding industrial environments, featuring robust optical isolation and comprehensive fault protection. Its dual-protocol support—including Modbus RTU and Profibus—ensures seamless integration into both legacy and modern automation networks, particularly within power generation and petrochemical sectors.
