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 ...

Embarking as an upgrade to the TG series timers, the latest additions include power-relay output options of 15A, 20A/1.5 HP, or 30A in either SPST or SPDT configurations. Timing functions include ...

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 ...

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 PCI-1763UP has eight optically isolated digital inputs with 2,500-Vdc isolation protection for collecting digital inputs in noisy environments and eight Form-C relay actuators for on/off control.

Programmable logic controllers (PLCs) and computer-based controllers are great for handling logic and data-collection tasks for industrial controls. But when it comes to driving motors, heaters, ...

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 ...

Inspired by input from panel builders, system integrators and end users around the world, Rockwell Automation engineers developed the new Allen-Bradley E300 electronic overload relay. The E300 ...

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, ...
