What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...

This circuit is designed to provide delayed relay switching action at power on. The delay is a function of the time constant produced by the combination of R1 and C1. At power on, C1 charges slowly ...

Panasonic has produced a 6pin DIP-style opto-relay that can switch 1.2kV at 750mA. Called AQV209G, it comes in through-hole and surface-mount versions and has a single ac-dc output with two mosfets ...

This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s). It utilizes a current transformer, single ...

FCL Components has introduced signal switching relays for electric vehicle power monitoring. “Conventional signal relays have often been used to switch signals for on-board equipment in electric ...

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...
