DAI01 | ABB | Isolated Analog Input Module for Freelance

Product Description

High-Resolution Analog Signal Acquisition

The DAI01 is a dual-channel analog input module engineered for the ABB Freelance distributed control system (DCS). Designed to bridge field instrumentation with the process station, the DAI01 provides isolated signal conditioning for standard industrial loops. Each channel is equipped with independent galvanic isolation to prevent ground loops and protect the control logic from electrical interference. Whether measuring pressure, temperature, or flow, the DAI01 ensures that analog variables are converted into precise digital values with high deterministic reliability.

Detailed Technical Specifications

The DAI01 module is optimized for versatility, allowing hardware configuration for both voltage and current sensing modes without requiring separate specialized hardware.
