What is the point of reviewing a cheap timer module, especially if it is based on the ubiquitous 555 timer chip? Recently I got an ‘updated’ version of the common 555 timer relay module. This time it ...

Relays play a crucial role in electrical protection, serving as intelligent switching devices that detect faults and initiate necessary actions to safeguard electrical systems. Acting as the first ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

A time delay relay controls the timing of electrical circuits by delaying switching operations. Commonly used in HVAC systems and motor control, it enhances safety, prevents equipment damage, and ...

I've been doing a lot of relay-based projects lately; building several light timer projects. The first couple used Arduino-class devices, simple relays and provided the ability to set multiple on and ...

Teledyne Relays introduced a new multi-function timer series—the Multi-Function Timer MFT. The user-friendly design features three potentiometers for easy selection of timing functions and ranges, ...

The CT-ERC.22 is a single-function electronic time relay from the CT-C timer range. It provides an ON-delay (delay on make) function with 7 time ranges from 0.05 s to 100 h. This time relay operates ...

We have received the Seeed Studio 2-Channel Wi-Fi AC Relay for review. It is an IoT/Smart Home device featuring a 2-channel relay (wet contact) that operates over a WiFi network, and provides an ...
