Description
Product Overview
The ABB DAO01 is a high-performance analog output module designed for industrial automation systems, specifically engineered to convert digital signals into precise analog outputs for process control and monitoring. As part of ABB’s Freelance 2000 distributed control system (DCS), this module plays a critical role in applications requiring accurate signal conditioning for actuators, valves, and other field devices. The DAO01 supports multiple output ranges, including 4-20 mA and 0-10 V, ensuring compatibility with a wide array of industrial equipment. Its robust design and advanced diagnostics capabilities make it suitable for harsh environments, such as chemical plants, power generation facilities, and oil refineries, where reliability and precision are paramount.
Featuring 16 isolated output channels with individual signal conditioning, the DAO01 delivers stable and interference-free analog signals. Each channel supports a 250 mA current output at 24 VDC or 125 mA at 48 VDC, providing flexibility for different load requirements 2122. The module’s 12-bit resolution ensures high precision in signal reproduction, while its ±0.1% accuracy minimizes errors in critical control loops 519. With RS485 and Modbus RTU communication protocols, the DAO01 integrates seamlessly with ABB’s AC800M controllers and third-party systems, enabling centralized monitoring and control of complex processes.
The DAO01 is built to withstand extreme conditions, with an operating temperature range of -20°C to +60°C and IP20-rated protection against dust and solid particles 1421. Its compact form factor (203 mm × 51 mm × 330 mm) and DIN rail mounting design optimize space in control cabinets, while the hot-swappable feature allows for quick replacement without system downtime. By combining ABB’s industrial-grade reliability with advanced signal processing capabilities, the DAO01 enhances operational efficiency, reduces maintenance costs, and ensures long-term system stability.
