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, ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

Hybrid relays combine a mechanical switch with a solid-state switch, and they are set up in parallel to control a single load.

Abstract: REQUIREMENTS for relay circuits are usually stated on a cause and effect basis; that is, when certain events occur in a particular way, certain effects will be produced. If a clear logical ...

This is a reference implementation aimed at introducing the key concepts of Conversation Relay. The key here is to ensure it is a workable environment that can be used to understand the basic concepts ...

Abstract: The Moore-Shannon model for switching circuits is extended to show how the number of redundant relays needed to improve reliability depends on the logical function of the entire circuit. The ...
