8-CH 12V ULN2003 Based Relay Board
8-CH 12V ULN2003 Based Relay Board
The 8-CH 12V Relay can control any device just like a switch contact. Its contact is isolated from the driven circuit. Features: LED Indication of Relay ON. Power Indication LED. ULN2803 Relay Driving IC. ON/OFF Power Switch. Direct input from 3-5V Microcontroller for relay control. Output terminal for relay contacts. Provision of the male header for wire connection. Powered from external 12V or from the male header. Contact Rating: 5A at 240V AC
Note: It is important that the microcontroller share ground with the relay board along with other control signals else it will not able to control the relay.
