Description
Product Overview
The ABB CPU0002 is a versatile and powerful central processing unit module designed for use within the ABB Freelance 800F distributed control system (DCS). This controller serves as the intelligent brain for small to medium-scale process automation applications, blending the ease of use of a PLC with the robust functionality of a DCS. It executes control logic, manages communication networks, and coordinates all connected I/O modules to ensure precise and reliable process operation.
Engineered for demanding industrial environments, the CPU0002 provides deterministic control performance and supports a comprehensive suite of automation functions, including sequential, regulatory, and batch control
