6.3 Appliance Wiring (Dry Contact)

The module provides dry contact outputs (NO, COM, NC) for each of its four channels. This means the relay acts as a switch without providing voltage. You will need to wire your appliance's power circuit through the relay contacts.

• E masani ona tatala (LEAI): The circuit is open (off) when the relay is de-energized and closed (on) when energized.
• Common (COM): O le vaega autū masani mo le relay.
• Normally Closed (NC): The circuit is closed (on) when the relay is de-energized and open (off) when energized.

Connect one side of your appliance's power line to the COM terminal and the other side to either the NO or NC terminal, depending on your desired default state.
