The ABB DAI01 is a high-precision analog input module designed for integration within the ABB Freelance and AC500 PLC control architectures. It functions as a specialized acquisition interface, converting analog field signals—such as temperature, pressure, and flow—into digital data for the central controller. Known for its exceptional accuracy of ±0.1%, the DAI01 provides channel-to-channel isolation to eliminate cross-talk and common-mode noise in heavy industrial environments. Whether utilized in chemical processing or power generation, this module ensures the integrity of process variables through robust signal conditioning and built-in electrical protection.
