Learn how to test and debug relay logic circuits for electrical controls with this guide. Follow six steps to check inputs, outputs, logic, scenarios, and documentation.

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

MAINTENANCE of stability on modern interconnected high capacity transmission systems is made considerably easier by the use of relays which not only operate extremely rapidly on line faults, ...

Abstract: The authors have proposed an RF adaptive array antenna loaded with reactance control circuits configured with variable capacitors. In this paper, the optimization algorithms for the variable ...
