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 ...

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 ...

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 ...

One of the frustrating challenges in integrating systems is interfacing an existing subsystem with a new or different subsystem. In cases where the input/output ...

Designed for high-voltage protection in industrial control and monitoring applications, the PCIe-IDIO-24 PCI Express I/O card boasts 24 optically isolated digital inputs and 24 solid-state FET relay ...

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 ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “TLP3910,” a photovoltaic-output photocoupler (“photovoltaic coupler”) housed in a thin SO6L package, ...
