PCD235A101: Product OverviewThe PCD235A101 is a high-performance controller module for ABB’s Symphony™ Plus distributed control system (DCS), designed for medium to large-scale process automation applications. This controller functions as the computational core of the DCS, executing complex control strategies including continuous regulatory control, batch sequencing, and advanced process optimization algorithms. Installed in a Symphony Plus cabinet, it interfaces with I/O modules to acquire process data from field instruments and executes control logic to maintain process variables within specified setpoints.The controller operates as part of a redundant architecture where two PCD235A101 modules can be configured in a hot-standby configuration, ensuring continuous process operation even during a controller failure. It runs the control application program developed with ABB’s Symphony Plus engineering tools, processing real-time data and executing control commands with deterministic performance. The controller’s design focuses on high availability, cybersecurity, and seamless integration with enterprise-level systems for comprehensive plant-wide automation.
