Connection 8 Channel Relay Board Circuit Diagram. This module are work same. The driver circuit for this relay module is slightly different compared to traditional relay driving circuits since there is an optional additional.
On board voltage regulator u1 7805 provides 5v dc supply to ongoing interface circuit connected to this board. The driver circuit for this relay module is slightly different compared to traditional relay driving circuits since there is an optional additional. Description 8 channel relay board is a simple and convenient way to interface 8 relays for switching application in your project.
Each relay on the board has the same circuit and the input ground is common to all eight channels.
This is a 5v 8 channel relay interface board be able to control various appliances and other equipment with large current. It can be controlled directly by micro controller raspberry pi arduino 8051 avr pic dsp arm arm msp430 ttl logic 5v 8 channel relay interface board and each one needs 15 20ma driver current. Each relay on the board has the same circuit and the input ground is common to all eight channels. This is a 5v 8 channel relay interface board be able to control various appliances and other equipment with large current.
