Rating: 100 % of 100. 8 Channel 5V Solid State Relay Module Board.OMRON SSR 4 PIC ARM AVR DSP Arduino. To power from an external supply simply connect the board GND to the Arduino GND, connect VCC to the Arduino VCC and connect your external supply -ve to GND and +ve to JD-VCC. System Wiring Blower Motor L ML MH H C R Y W G 123456 123456 A/C O.D. 8 Channel Relay Board is a simple and convenient way to interface 8 relays for switching application in your project. When analyzing the operation of a relay control system, it is helpful to have some way to temporarily denote the conductive status of switch contacts and the energization status of relay coils (i.e. Up to 8, 12V SPDT relay control; Industry standard relay drive IC – ULN2803 If you continue to use this website without changing your cookie settings or you click "Accept" below then you are consenting to this. Relay module for Arduino is one of the most powerful application for Arduino as it can be used to control both A.C and D.C devices by simply controlling the relay by giving 5V. It can be used to control various appliances and equipment with large current. SKU. Section SPECIFICATION This item has been assembled, and electrical test passed. A relay can be used to control high voltages with a low voltage by connecting it to an MCU. Relays are suitable for driving high power electronic devices such as lights, electric fans and air condition. Please refer to the schematic diagram for the configuration of this board.
