ABB DAI03

The ABB DAI03 is an analog I/O module developed by ABB for the Freelance 2000 Distributed Control System (DCS), primarily used for analog signal acquisition and control in industrial automation processes. Depending on the system configuration, the DAI03 can function as either an Analog Input (AI) or Analog Output (AO) module, enabling the exchange of analog data between field instruments and the control system.

Main Functions

• Collects analog signals from transmitters, sensors, and other devices.
• Converts digital signals from the controller into standard analog signals.
• Supports real-time monitoring and control of industrial process parameters.
• Provides high-precision data interfaces for process variables such as temperature, pressure, flow, and level.
• Seamlessly integrates with the ABB Freelance 2000 control system.

Features

• High-precision analog signal processing capability.
• Excellent anti-interference performance and industrial-grade reliability.
• Modular design for easy installation and maintenance.
• Suitable for continuous operation in industrial environments.
• Applicable across power, petrochemical, metallurgy, water treatment, and paper industries.

Technical Information

Typical Applications

• DCS process control systems
• Power plant automation
• Petrochemical process control
• Water treatment and environmental engineering
• Pulp and paper production lines
• Metallurgy and mining automation

The ABB DAI03 module is widely used in industrial automation scenarios requiring highly reliable data acquisition and process control, thanks to its stable analog signal processing capabilities and full compatibility with the Freelance 2000 system.
