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 ...

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 ...

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 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 ...

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 ...

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 ...

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 ...

Higher amperage relay output modules and an 8-point input simulator module are now available from AutomationDirect for the Click series stackable micro brick PLCs. The Click C0-04TRS-10 ($54.00) is a ...
