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 ...

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 ...

[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.

Our Radio World colleague Charles S. “Buc” Fitch, P.E., recently completed a relay interface assembly for controlling an older auxiliary transmitter. Late-model transmitters have remote control ...

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 ...

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.

The system converts CAN-interface control signals (twisted pair or single-mode fiber) into relay control signals of railroad automation systems. The M-Max 400 RC leverages two-out-of-two ...
