PLC (Programmable Logic Controller) is a crucial component in industrial automation, designed to control and automate machinery and processes. This category includes a wide range of PLCs, from compact models for small-scale applications to modular systems for complex industrial tasks. Key products in this category encompass PLC hardware (such as CPUs, I/O modules, and communication interfaces), programming software (e.g., ladder logic and structured text editors), and accessories (like power supplies and mounting racks). PLCs are known for their reliability, scalability, and real-time performance, making them ideal for manufacturing, robotics, and process control. Features often include high-speed processing, robust communication protocols (e.g., Ethernet/IP, Profibus), and compatibility with various sensors and actuators.
