Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

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 ...

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 ...

Operating from a 24-Vdc isolated power supply, the devices use an input control from 4 to 20 mA or 0 to 10 Vdc. Features of the relays include an integral heat sink for controlled cooling, DIN-rail ...

This 12V solar charge regulator meets most small-scale application requirements. With a current rating of 6A, it can handle up to a 100W solar panel. Its principle of operation is very simple and ...

The microBlox signal conditioning modules from Acromag plug into the company’s uBTA Transmitter Alarm Carriers to provide threshold value switch and process signal output capabilities. Single and dual ...

Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...
