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 ...

Expanding the SeaDAC family of USB data-acquisition devices, the SeaDAC PLC-16H digital I/O module combines high-current Form C relay outputs and optically isolated inputs. It includes eight SPDT high ...

Solid-state relays are much smaller than corresponding single-pole relays. They are also faster, dissipate less power, and withstand a larger number of operations. And unlike electromechanical relays, ...

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, ...
