5.1 Precauzioni di sicurezza

AVVERTIMENTO: L'installazione comporta un alto volumetage. Ensure power is disconnected at the circuit breaker before performing any wiring. If you are unsure about electrical wiring, consult a qualified electrician. Improper installation can lead to electric shock, fire, or property damage.

5.2 Schema elettrico

The device features screw terminals for input power and four independent relay outputs. Each output has Normally Open (NO), Common (COM), and Normally Closed (NC) contacts.

• Potenza in ingresso: Connect AC 85-250V to the 'Input 85-250V' terminals. Alternatively, for low-voltage applications or testing, connect a 5V Micro USB power supply to the Micro USB port.
• Load Connections (Channels K1-K4): Each channel (K1, K2, K3, K4) has three terminals:
• NC (normalmente chiuso): Connected to COM when the relay is OFF.
• COM (Comune): Il terminale comune per il relè.
• NO (normalmente aperto): Connected to COM when the relay is ON.

Connect your appliance's power line to the COM terminal and the control line to either NO or NC, depending on whether you want the appliance to be ON or OFF when the relay is activated.

6. Modalità operative

The EWB4CH-D1 supports three distinct operating modes, configurable within the eWeLink app:

• Point (Momentary) Mode: When activated, the relay turns ON for a set duration (0.5 seconds to 1 hour) and then automatically turns OFF. This mode is suitable for applications like garage door openers or momentary button presses.
• Self-Locking (Toggle) Mode: Each channel operates independently. When activated, the relay turns ON and stays ON until it is manually turned OFF. This is ideal for controlling lights or other devices that need to remain in a specific state.
• Modalità di interblocco: In this mode, only one channel can be ON at a time. When one channel is activated, any other currently active channel will automatically turn OFF. This is useful for controlling motors with forward/reverse functions or blinds.

To change the operating mode, access the device settings within the eWeLink app.
