3.1 Sambungan Bekalan Kuasa
The SH-BT01C module can be powered by either 5V DC or 12V DC. Connect the appropriate power source to the VCC and GND terminals on the input side of the module.
- Input 5V: Connect 5V DC to the '5V' terminal and ground to 'GND'.
- Input 12V: Connect 12V DC to the '12V' terminal and ground to 'GND'.
3.2 Sambungan Beban
The relay provides three output terminals: Normally Open (NO), Normally Closed (NC), and Common (COM). Select the appropriate connection based on your application's requirements.
- Biasanya Terbuka (NO): The circuit is open (disconnected) when the relay is de-energized and closes (connects) when the relay is energized.
- Normally Closed (NC): The circuit is closed (connected) when the relay is de-energized and opens (disconnects) when the relay is energized.
- Common (COM): This is the common terminal for both NO and NC connections.
