Description
A DDC control panel is a digital control system that manages various building services, including heating, ventilation, air conditioning (HVAC), lighting, and security systems. It utilizes digital signals from sensors and controllers to optimize building performance and enhance energy efficiency.
Key Components of DDC Panels
Processor: The brain of the DDC panel, responsible for processing inputs from field devices and sending appropriate outputs. Common processors include Programmable Logic Controllers (PLCs) and Building Automation Controllers (BACs).
1
Input/Output Modules: These modules provide various functions, including analog and digital inputs and outputs. They can be universal (for any I/O function) or dedicated (for specific functions).
1
Control Transformer: Reduces the voltage supply to a safe operating level for the DDC panel components.
1
Relays: Used for switching high-power loads on and off, acting as an interface between the control system and field devices.
1
Terminal Blocks: Provide secure connections for wiring between components
