Modern automation wouldn’t be the same without programmable logic controllers. PLCs are ruggedized computers that constantly monitor sensor input to control output, and play an integral role in everything from assembly lines, to roller coasters, to lighting systems.

Frequently asked questions
A programmable logic controller or PLC is a solid-state computer designed for the manufacturing industry. PLCs monitor the information they get back from input devices and then make decisions based on that state. Those input devices that the PLC devices monitor are attached to industrial machines used in manufacturing processes. The PLC can adjust the way these machines operate based on this feedback. PLCs started replacing relay logic systems in the 1960s, as they are more reliable and easier to troubleshoot than the older relay-based system. Because of the harsh environments where PLCs must operate, their design is rugged enough to withstand extreme temperatures and shock. They are also programmable and modular, so technicians can tweak a manufacturing process with code and apply the same change elsewhere by just copying its code.
