Relay Module Schematic Diagram

On that page it has a wiring diagram the pins are hard to see in the pic the main block is gnd in1 in2 in3 in4 in5 in6 in7 in8 vcc the smaller block with the jumper is gnd vcc jd vcc. All four relays are connected with arduino at 8910 and 11th pins in1 in2 in3 and in4 and 1 12v adapter is used for powering the circuit. Red refers to errors.

Typical connection to an arduino.

Relay module schematic diagram. It works with the 8. For demonstrating the working of this relay module we have used an arduino uno board for controlling relays. The drawing below shows the typical connections to an arduino. 12 volt relay wiring schematic.

The real benefit behind a relay is more than automation. We would like to show you a description here but the site wont allow us. Variety of 12 volt solenoid wiring diagram. Fundamentally this is four separate circuits on one board.

In electromechanical relays the coil accomplishes this function. Vcc and ry vcc are also the power supply of the relay module. The purpose of a relay is to automate this power to switch electrical circuits on and off at particular times. 5v arduino four channel relay schematic.

See the schematic below. Solid state relays however normally have only one output contact. Now i assume the jumpers allows the relay module to take power from the vcc of the main pin block. Car qook automotive dc 12v 12 volt 30a amp spdt wiring power relay.

A relays output circuit is the portion of the relay that switches on the load and performs the same function as the mechanical contacts of electromechanical relays. Quad channel relay board is a simple and convenient way to interface 4 relays for switching application in your project. With the vcc and jd vcc jumpered. When you need to drive a large power load you can take the jumper cap off and connect an extra power to ry vcc to supply the relay.

All of these features make sainsmart relay a great component for automation projects. Other than sharing vcc and ground the channels are isolated from one another. How to wire a raspberry pi to a sainsmart 5v relay module related product strongly recommended sainsmart 8 channels wifi remote control model. 555 integrator with transformer relay with relay schematic circuit diagram audio spectrum analyzer dspic30f6012 mcp6022 hand held simple magnetized demagnetized device schematic circuit diagram.

3 terminals per spdt relay. Input supply 12 vdc at 170 ma.
