8 Channel Relay Board Circuit Diagram

After all parts you collected lets go ahead to the next step.

8 channel relay board circuit diagram. When set 1 and reset 0 q 1 output is shown. 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. Input supply 12 vdc 336 ma output eight spdt relay relay specification 5 a 230 vac. Don t skip this step it is necessary to avoid mistakes when soldering into a pcb and check if it is works.

Dual relay driver board electronic circuit diagram dual channel relay board is a simple and convenient way to interface 2 relays for switching application in your project. Channel relay board is a simple and convenient way to interface 8 relays for switching application in your project. Connect the signal terminal in4 in5 of 8 channel relay to digital port 3 2 of the sunfounder arduino mega2560 board and connect an led at the output terminal pay attention to that there are only two submodules of the 8 channel relay are used in this example but you can use the 8 submodules freely 8 channel relay arduino mega2560. By circuit diagram this is a 8 channel relay interface board using uln2803.

8 channel relay board is a simple and convenient way to interface 8 relays for switching application in your project. Easy interface with microcontrollers based projects and analog circuits. The output table and the relay made by the sr flip flop circuit are shown in figure 1 8. Input 12 vdc 84 ma.

All the relays are opto isolated using optocouplers and can be controlled directly using a microcontroller of any kind arduino 8051 avr pic dsp arm arm msp430 ttl logic or a pc. 636 723 4000 products page r8spi 8 channel opto isolated relay board with spi interface the industrologic r8spi is a versatile opto isolated serial peripheral interface spi interface 8 channel relay board that can add medium current form c relays not only to industrologic products but to a wide variety of microcontroller outputs logic circuits and plcs as well. A cycle that controls the start and stop of a load by two buttons is called a sealing cycle. Now we have all the parts to make a diy relay module.

Input 12 vdc 336 ma output eight spdt relay relay specification 5 a 230 vac trigger level 2 5 vdc.
