Littelfuse, Inc. a global manufacturer of leading technologies in circuit protection, power control, and sensing, announced the PLA172P OptoMOS® Relay, an 800 V normally-open single-pole 6-pin solid-state relay (SSR). It is the first solid-state relay in the Littelfuse product...

This sound sensor with Relay driver shield for Arduino Nano can be used to develop sound-activated ON/OFF switch or other projects that require sound senor. LM358 op-amp is used as the amplifier, 1st op-amp amplifies the microphone signal, and 2nd op-amp works as a half-bridge rectifier...

Bridgetek has further extended the scope of possibilities addressed by its PanL home automation connectivity platform - with release of the PanL Relay. The purpose of this latest unit is to bring greater functionality to installed systems, thereby leading to heightened levels of...

OMRON Corporation of Kyoto, western Japan globally released its new MOS FET (*1) relay module “G3VM-21MT” on December 2, 2019. The product is the first electronic component in the world (2) to adopt a “T-type circuit structure” (3). With a T-type circuit structure...

Out of curiosity I ordered a tiny ESP8266 relay switch board from aliexpress.com, for next to nothing. Blissfully unaware, then, of the struggle ahead to make the thing work as advertised. I survived and conquered — here’s the story. By Somnath Bera @ elektormagazine.com The little...

Tiny device features lower input power to reduce equipment size and power consumption Toshiba Electronics Europe (“Toshiba”) announces the availability of a new voltage driven photorelay with a tiny S-VSON4T package and reduced input power dissipation. The new product, designated...

A window detector circuit, also called window comparator circuit or dual edge limit detector circuit is used to determine whether an unknown input is between two precise reference threshold voltages. It employs two comparators to detect over-voltage or under-voltage condition. This...

Clever way of starting-up relays discussed in this app note from Maxim Integrated. via dangerousprototypes.com Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the...
