What does DDC stand for in controls?
direct digital control
It’s for this reason that many industrial, commercial, and other buildings such as schools, apartment complexes, and office spaces have dedicated direct digital control (DDC) systems.
What is building DDC?
DDC systems are used to control a building’s various systems from one central point. A building may incorporate a DDC system just to control its HVAC (heating, ventilation and air conditioning) system, or to automate the entire building by also controlling other mechanical and electrical systems.
What are the benefits of DDC?
Other advantages of DDC controls include:
- Increased occupant comfort.
- Decreased operating costs and faster response time.
- Controls sequences for energy savings.
- Digital interface.
- Less tenant maintenance required.
What is difference between PLC and DDC?
A programmable logic controller (PLC) is a ruggedized hardware device with a dedicated CPU and internal operations system used in industrial automation. A direct digital control (DDC) is a computer-based control process in which the computer acts as a controller.
What is a DDC in audio?
In digital signal processing, a digital down-converter (DDC) converts a digitized, band-limited signal to a lower frequency signal at a lower sampling rate in order to simplify the subsequent radio stages. The input and output signals can be real or complex samples.
What is the function of direct digital control?
Direct digital control (DDC) is a control process in which a microprocessor controller constantly updates an internal information database by monitoring information from a controlled environment and continuously produces corrective output commands in response to changing control conditions.
Who is DDC and what do they do?

DDC is a leader in high reliability transformer, magnetic and cable assembly solutions for the aerospace, defense, and space industries, w…
What are the functions of a DDC control unit?
The System Control Unit or SCU supports many functions provided by the Enviro-Tec DDC control system. Among these functions are: 1. Internal Clock/Calendar function for mode and auxiliary contact scheduling. 2. Modem communications support for the entire system.
What does DDC stand for in power conversion?
DDC offers proven smart power control and power conversion solutions that enable land, sea, air, and space vehicle systems the ability to control and distribute raw and conditioned power, more efficiently and reliably.
How is BTC used in a DDC system?
This BTC control sequence, powered by 24 VAC control voltage from the BPV01, gives stand-alone DDC static pressure control by providing 24 VAC damper open and damper close signals to control in parallel 1, 2 or 3 bypass terminals. The bypass control BTC01 is used in systems with a constant volume supply fan.
