Check out this link for On Semiconductor’s datasheet for a line of “Zero-Cross Optocoupled Triac Drivers.” The ability to zero-cross when turning on AC line voltage to some loads may be advantageous.

Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these ...

Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...

When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

Modern relay technology has been around since the 1960s, and its main function is to provide automation with electrical isolation for many applications. All relays have two separate circuitries: input ...

THE ISOLAR BX SOLAR SYSTEM CONTROLLER is a multi-functional differential controller that can be used in a wide variety of solar heating applications. It features four relay outputs — three are triac ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.
