This is a simple circuit which I built to one of my audio amplifier projects to control the speaker output relay. The purpose of this circuit is to control the relay which turns on the speaker output ...

The MAQ20-DORLY20 module offers 20 isolated SPST latching relay output channels that can switch between 2 A at 30 V and 0.4 A at 150 V. Each channel has contact state readback to verify the physical ...

Achieve max electric fuel pump output and safety using a relay plus an oil pressure safety switch. Achieving maximum output and safety with a custom-wired electric fuel pump requires a properly ...

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 ...

Addressing the requirements of power switching applications, the ADAM-6066 relay-output module includes Ethernet connectivity, an embedded web server for remote monitoring, and support for Modbus/TCP ...

No matter what the application is, when a definite-purpose solution is required, time delay relays (TDRs) can provide simple, reliable, and economical control. Adjusting the delay time is often as ...

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 ...

Recently, [Manuel] did a post on making logic gates out of anything. He mentioned a site about relay logic. While it is true that you can build logic gates using switch logic (that is, two switches in ...

The CPC1333 is a single-pole, normally closed optoMOS® relay featuring 5000 Vrms input/output isolation voltage and blocking voltage of 350 Vp. It is 100% solid state and offers low drive power ...

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 ...

Ready-made wiring harness and relay kit makes it easy to add relays to a motorcycle headlight. Adding a relay can improve headlight output, reduce load on switches and allow higher wattage bulbs to be ...
