Digital Controls
Digital controls are microprocessor-based systems that transform modern air compressors into highly efficient and intelligent machines. They allow for the precise management of a compressor’s functions, saving energy and enhancing reliability.
Digital controls monitor and regulate key operational parameters such as temperature, pressure and engine speed. By intelligently adjusting the compressor’s output to match real-time demand, these controls significantly decrease energy consumption.
FAQs
Logic controls typically refer to programmable logic controllers (PLCs), specialized electronic devices that use programmed instructions to control machinery and industrial processes. They act as the brain of an automated system, making decisions based on a set of preprogrammed logic by taking in signals from sensors and sending out commands to actuators, valves and motors.
Direct digital controls (DDCs) are digital control systems that use microprocessors to automatically manage equipment. A DDC manages air compressors by reading pressure and temperature sensor data, processing the data according to its programming and sending commands to the compressor’s operating components, such as motors and valves.
PLCs and DDCs are computer-based controllers that automate an air compressor’s function. The primary difference lies in their application and robustness.
PLCs are industrial-grade digital computers designed for harsh manufacturing environments and for mission-critical processes. They are faster, more flexible and more reliable, making them the preferred choice for complex industrial air compressor applications and integration into larger plant automation systems.
In contrast, DDCs are commonly used for less demanding applications such as building automation.
A digital control system is a broad term for the technology that uses digital controllers, such as PLCs or DDCs, to manage an air compressor. In the context of industrial automation, this system is crucial for integrating the compressor into the larger factory ecosystem.
It allows the compressor to operate automatically, respond to real-time changes in air demand and communicate its status, performance data and alarms to a central plant management system.
Through PLC programming, advanced logic controllers are configured with the specific capacity and efficiency of each compressor in the system. This enables the controller to make intelligent decisions about which compressor or combination of compressors to run to meet the demand most efficiently.
Yes, this is a major advantage of modern digital controls, particularly those using PLCs. PLCs are designed for industrial communication and easily integrate into a plant’s central control system. This integration allows for centralized monitoring, improved efficiency and data analysis.
The primary benefit is a significant reduction in energy consumption, with potential savings. Digital controllers achieve this by precisely matching the compressor’s output to the air demand, avoiding unnecessary energy expenditure.
Yes, you can retrofit digital controllers to older models, providing them with modern automation, enhanced efficiency and remote monitoring capabilities.
