logiikkaohjaimilla

Logiikkaohjaimet, known in English as logic controllers or programmable logic controllers (PLCs), are industrial computers designed for controlling manufacturing processes. They are used to automate electromechanical processes such as assembly lines, robotic devices, or any activity that requires high reliability control and process fault diagnosis and simple programming. Logiikkaohjaimet are ruggedized to withstand harsh industrial environments and are built for a wide range of temperatures, electrical noise, vibration, and humidity.

The primary function of a logiikkaohjain is to read input signals from sensors and devices, process these signals based on a programmed logic, and then control output devices such as motors, valves, and lights. The programming of logiikkaohjaimet typically involves ladder logic, function block diagrams, or structured text, which are designed to be easily understood by electricians and technicians.

Logiikkaohjaimet have become indispensable in modern industrial automation due to their flexibility, reliability, and cost-effectiveness. They allow for precise control, efficient operation, and quick adjustments to production lines. Compared to older relay-based control systems, logiikkaohjaimet offer significant advantages in terms of programmability, diagnostics, and scalability, enabling industries to improve productivity and reduce downtime.
