PLC (Programmable Logic Controller) is a rugged, industrial-grade computer designed to monitor inputs, process logic, and control outputs in real time. Widely used in manufacturing and automation, PLCs act as the “brain” of machines and processes, ensuring precision, reliability, and efficiency. They can automate tasks such as machinery control, assembly lines, and safety systems, while withstanding harsh industrial environments like high temperatures, vibration, dust, and exposure to chemicals.
