PLC or Programmable Logic Controller
A PLC or Programmable Logic Controller is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices. Almost any production line, machine function, or process can be greatly enhanced using this type of control system. However, the biggest benefit in using a Programmable Logic Controller is the ability to change and replicate the operation or process while collecting and communicating vital information. Another advantage of a Programmable Logic Controller system is that it is modular. That is, you can mix and match the types of Input and Output devices to best suit your application. PLC controllers have been an integral part of factory automation and industrial process control for decades. Programmable Logic Controllers control a wide array of applications from simple lighting functions to environmental systems to chemical processing plants.
These systems perform many functions, providing a variety of analog and digital input and output interfaces; signal processing; data conversion; and various communication protocols. All of the Programmable Logic Controllers components and functions are centered around the controller, which is programmed for a specific task. The basic Programmable Logic Controller module must be sufficiently flexible and configurable to meet the diverse needs of different factories and applications. Input stimuli (either analog or digital) are received from machines, sensors, or process events in the form of voltage or current. The Programmable Logic Controller must accurately interpret and convert the stimulus for the CPU which, in turn, defines a set of instructions to the output systems that control actuators on the factory floor or in another industrial environment. PLC Technologies offers a wide range of Programmable Logic Controllers to the Industry.
