Industrial control is a broad category of electrical components that are among the most important parts of modern automation environments and are appropriate for any industry.
Industrial control systems can range from a few panel-mounted controllers and contactors to large distributed control systems with thousands of inputs and outputs. Controllers receive data or prompts from sensors to compare measured variables and conditions, and initiate control elements down the line to start or stop motors, open or close valves, and much more.
Modern industrial control systems capitalize on complex HMI (human machine interface) equipment and advanced industrial networking techniques to deliver commands and information in real time. New solid state relays transmit commands instantly, and PLCs (programmable logic controllers) actuate huge networks of interdependent equipment in precise order and timing. As a result, many processes benefit from improved efficiency.
