Altech Process Controllers
Process controllers are electronic devices used in industrial processes to monitor and adjust various parameters such as temperature, pressure, flow, and composition. They consist of a central processing unit (CPU) and input/output (I/O) modules which receive signals from sensors and send control signals to actuators. The CPU processes the input signals and uses a control algorithm to determine the appropriate output signals to maintain the desired process parameters.Electronic components play a crucial role in the functioning of process controllers. The CPU is usually made up of integrated circuits that contain the necessary processing power and memory. Analog-to-digital converters (ADCs) are used to convert the analog signals from the sensors to digital signals that can be processed by the CPU. Digital-to-analog converters (DACs) are used to convert the digital control signals into analog signals for the actuators.Other electronic components such as transistors, resistors, and capacitors are also used in the design of process controllers to ensure proper signal conditioning and protection against electrical noise. The use of advanced electronic components has made modern process controllers more accurate, reliable, and versatile, making them an essential tool in the automation and control of industrial processes.
