In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one ...

No matter what the application is, when a definite-purpose solution is required, time delay relays (TDRs) can provide simple, reliable, and economical control. Adjusting the delay time is often as ...

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals.

Most industrial facilities include electric motors that require overload relays for protection, control and monitoring purposes. The latest overload relays are often called motor management relays ...

Application areas and power ratings are the two main factors that differentiate relays from contactors though both styles of devices may use the same basic switching mechanisms ...

Five Microseries relays designed for use in hazardous locations are the latest additions to the vendor’s line of Class 1 Division 2 approved products.

Control relays are usually designed to switch small control circuit currents. Common types of timing relays are ON-delay (delay on operate), OFF-delay (delay on release), interval delay, and repeat ...

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 ...

Phoenix Contact has expanded its range of safety process relays. The PSR-FSP2/2x1 and PSR-FSP/2x1 process safety relays are safe interposing relays specifically designed to operate with fail-safe ...
