More details are given in the Ladder logic."
- 16:5916:59, 10 February 2024 diff hist +527 N Glossary:PLC Created page with "A PLC or Programmable Logic Controller is a device much used in industry for controlling plant and machinery. It has a number of inputs which would be connected to sensors of different kinds, and outputs through which it can control switches, valves, motors, pumps etc in order for the machine or industrial process to operate correctly and safely. Their pre-electonic origins lie in relay logic and they are still normally programmed by similar Wikipedi..."

A phase difference is measured in degrees; 360 degrees represents a complete cycle so is the same as no phase difference, whereas with a phase difference of 180 degrees, the peak of one wave will coincide with the trough of the other and combined, they will cancel out." current

Class A drives the output throughout a cycle, and is the least efficient. Class B drives the output for only a half cycle. Usually, a second Class B driver drives alternate half cycles. Class C drives the output for less than half a cycle and generally drives a tuned circuit to restore the output (typically in a transmitter) to a p..."
- 11:4911:49, 19 January 2024 diff hist +314 N Glossary:PWM Created page with "PWM or Pulse Width Modulation is a highly efficient method of power control in which the power is switched on and off very rapidly. The ouput is then smoothed with a capacitor and/or inductor and the relative on and off times then determine the power that is delivered."
