Because the wiring and the inputs and outputs (I/Os) are the most vulnerable elements in a system, be sure to locate and identify these elements in the problem circuit. Sometimes, the only way to test ...

The programmable logic controller (PLC) is a microprocessor-based system that accepts input data from switches and sensors, processes that data by making decisions in accordance with a stored program, ...

Programmable logic controllers (PLC) save time, money, and energy in process control systems. They simplify systems. A brief history of manufacturing processes sets the stage for how to use modern ICs ...

Digital/binary sensors and switches are essential for signal monitoring and system control in industrial control, industrial automation, motor control, and process automation. All the sensors’ outputs ...

AutomationDirect announces the release of a new White Paper, “Basic Pneumatic Circuits”, which discusses common pneumatic circuits that can be used alone or as building blocks in larger pneumatics ...
