8 Channel Relay Board Circuit Diagram

The output table and the relay made by the sr flip flop circuit are shown in figure 1 8.

8 channel relay board circuit diagram. 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. By circuit diagram this is a 8 channel relay interface board using uln2803. Easy interface with microcontrollers based projects and analog circuits. Now we need to test the circuit diagram of the relay module on a breadboard.

Input 12 vdc 84 ma. Channel relay board is a simple and convenient way to interface 8 relays for switching application in your project. 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. Input 12 vdc 336 ma output eight spdt relay relay specification 5 a 230 vac trigger level 2 5 vdc.

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

Don t skip this step it is necessary to avoid mistakes when soldering into a pcb and check if it is works. 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. 8 channel relay board is a simple and convenient way to interface 8 relays for switching application in your project. A cycle that controls the start and stop of a load by two buttons is called a sealing cycle.

Input voltage level support ttl as well as cmos.
