Direct digital control (DDC) is best described as

• A. Electronic controls used for equipment control and monitoring
• B. A hydraulic control system
• C. Manual configuration and control
• D. An analog sensor

Answer: (A)

Direct digital control is about using electronic controllers that process digital data from sensors to automatically control equipment and monitor its performance. A DDC system relies on a microprocessor running software to interpret sensor readings, execute control logic, and send digital commands to actuators, enabling real-time, automatic adjustments and centralized or distributed monitoring. It differs from hydraulic control (fluid power), from manual configuration and control (no automatic processing), and from an analog sensor alone (the hallmark is digital processing and automatic control).
