Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...

CHICAGO--(BUSINESS WIRE)--Littelfuse, Inc., the global leader in circuit protection, announces the AF0500 Arc-Flash Relay, which delivers arc-flash protection in a flexible design with unlimited ...

Single-coil latching relays find use in signal-routing, audio, and automotive systems. To maximize their usefulness and cut power consumption, these coil currents must flow in both directions. Current ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

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.
