4. Configuració i instal·lació
- Connexió d'alimentació: Connect a 5V DC power supply to the module's DC power jack or the DC+ / DC- screw terminals. Ensure the power supply can provide at least 300mA. For 4-way and 8-way modules, this external power supply allows the relay state to be maintained even if the USB connection is lost.
- Connexió USB: Connect the module to your computer's USB port using a standard USB cable. The module will be recognized automatically as a HID device, requiring no additional driver installation.
- Connexió de càrrega: Identify the Normally Open (NO), Normally Closed (NC), and Common (COM) terminals for each relay.
- Normalment obert (NO): The circuit is open (disconnected) when the relay is de-energized and closes (connects) when the relay is energized.
- Normalment tancat (NC): The circuit is closed (connected) when the relay is de-energized and opens (disconnects) when the relay is energized.
- Comú (COM): El terminal comú per al commutador de relé.
