Often a need arise to interface output of the microcontroller with an electromagnetic relay (EMR). Relays are devices which allow low power circuits to switch a relatively high Current and/or Voltage ...

Advantages of the low side driver Easy to interface to low voltage logic circuitry Far more interface options including the popular ULN2003 driver Fewer components Uses more commonly available and ...

As [Mic] often got requests to make high-power switching boards, he recently finally gave in and designed the one shown above based around a solid-state relay. Some of our readers that already play… ...

PHOENIX CONTACT PLC-Interface provides an innovative combination of a relay interface and circuit breaker in an overall width of 6.2mm, thus saving valuable space in the control cabinet. The nominal ...

[Glitch] got his hands on a slew of relays which are meant for use in industrial equipment. They are designed to operate at 24V. He wanted to use these with common microcontrollers and instead of b… ...

This project contains the code for an ESP32 based relay controller, used by the author as Garage Door Opener. It consists of an Adafruit feather with relay board and some Python based web services.

IDEC Series RV8H 6mm interface relays save space and provide a compact solution for general purpose relay requirements. Products can be used as universal interfaces between the controller and the ...

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.

These 35mm DIN rail mount KPR series compact 6.2mm relay modules include LED indicators and integrated resistor, capacitor, and Zener diode (RCZ) filters on select models. Models are available with DC ...
