ABB DAO 01 0369629 24V DC 16-Channel Process Control Module

ABB DAO 01 (DAO01) 16-Channel Analog Output Module

The ABB DAO 01 (DAO01) is a high-density analog output expansion module engineered for ABB industrial automation and Freelance 2000 distributed control systems (DCS). Designed to provide precise loop control across complex process control architecture, this module converts digital controller signals into accurate 0/4–20mA analog current signals. Built into a compact rack-mountable form factor measuring 8.0" x 2.0" x 13.0" (20.3 cm x 5.1 cm x 33.0 cm) with a solid net weight of 1.7 kg (3.75 lbs), the DAO 01 delivers heavy-duty physical stability and reliable field device interfacing for process automation environments.

Key Performance Advantages

Equipped with 16 dedicated analog output channels, the ABB DAO01 module allows operators to seamlessly manage multiple control loops—such as control valves, variable frequency drives, actuators, and signal conditioners—from a single rack slot. Operating on a standard 24V DC power supply, it maintains low power consumption while delivering stable current loop drive across field loads up to 450 ohms. Channel isolation safeguards internal processor backplanes from electrical noise, voltage transients, and ground loops common in power plants, water treatment facilities, and manufacturing lines. With an operating temperature tolerance ranging from 0°C to 50°C, the DAO 01 ensures reliable round-the-clock performance in standard control cabinets.

Installation & Commissioning Guidelines

• Rack Insertion: Ensure system power is disconnected or hot-swap safety protocols are engaged prior to installation. Slide the 1.7 kg DAO 01 card smoothly into the target rack slot until edge connectors fully seat.
• Field Wiring: Connect 0/4–20mA analog output field devices to the corresponding terminal base channels. Ensure shielded twisted-pair cabling is grounded at one end to prevent EMI noise interference.
• Power Supply Verification: Confirm stable 24 V DC power supply to the module backplane before initiating channel parameter configuration within the system software.

Frequently Asked Questions

Q1: What type of output signals does the ABB DAO 01 module support?
A1: The module provides standardized analog current loop outputs (typically 0–20mA or 4–20mA) across all 16 channels to drive industrial process control devices.

Q2: What power supply voltage is required for operating the DAO01?
A2: The module operates on a nominal supply of 24 V DC, drawing minimal power to maintain cool, reliable operating temperatures within industrial enclosure racks.
