Beverly, Mass. — Designed to replace electromechanical devices, a new current limiting, normally open, 1 Form A optically isolated solid-state relay (SSR) from Clare Inc., an IXYS company, saves board ...

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, ...

With integrated diagnostics and override functions, PLCs have become easier to use and much less expensive. Before the automotive industry discovered the advantages of programmable logic controllers ...

Since the mid-1980s, semiconductor technology has promised to provide smart power products for solid-state relays that could carry high current and provide unique functions for customers. However, ...

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 ...
