PLC Controllers

 PLC Controllers
Programmable Logic Controllers (PLCs) are rugged industrial computers used to automate machines and processes in factories, plants, and other industrial environments. PLCs take inputs (from sensors, switches and buttons), processes logic (based on a programmed set of rules), and controls outputs (motors, valves, lights, alarms). Common applications for PLCs include assembly lines, robotic arms, conveyor systems, packaging machines, and sorting systems. 

Programmable Logic Controllers (PLCs) are in stock at Mouser and available for same day shipping. Mouser is an authorized distributor for many Programmable Logic Controller manufacturers including Arduino, IDEC, Industrial Shields, Omron, Opto 22, Phoenix Contact, Schneider Electric, Siemens & more.
