4 Channel Relay | Module Library For Proteus New

The 4-channel relay module library for Proteus that we will provide has the following features:

4-channel relays involve multiple components, which can slow down simulations.

Connect Arduino digital pins to IN1, IN2, IN3, and IN4 respectively.

: Early simulations required using the generic "RELAY" component from the Proteus Device Library

: Many modern libraries include the optocoupler isolation feature, protecting your simulated microcontroller from "virtual" back EMF. The 4-channel relay module library for Proteus that

A typical use case: controlling 4 household bulbs (simulated as DC motors or LEDs) via an Arduino Uno.
