A programmable logic controller, or PLC, is a software-based equivalent of a relay panel. A PLC is a general-purpose device. One model can be programmed to control a variety of machines, and programs ...
There are many vendors and sources of PLCs: Automation Direct, FactoryMation, B&B Electronics, and yes, even eBay, among others. I will use the Click PLC available from Automation Direct as an example ...
There are many industrial applications, such as programmable logic controllers, that require efficient, low cost, step-down power conversion over a wide range of voltage levels. This paper discusses ...
The modern programmable logic controller (PLC) is at the nexus of two debates that are taking place daily at opposite ends of the control-system spectrum. At one end is the debate over the ideal ...
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, ...
With an input-voltage range up to 75V, the LM5085, LM25085, LM5088, and LM25088 buck controllers can regulate output voltages as low as 1.2V at load currents in excess of 5A. Each offers a ...
