3. Setup and Wiring
This section details the connections and initial setup for your relay module. Ensure all power is disconnected before making any connections.
3.1 Module Interface Connections
- DC+: Connect this terminal to the positive pole of your power supply. The voltage must match the relay's operating voltage (e.g., 5V, 12V, or 24V).
- DC-: Connect this terminal to the negative pole (ground) of your power supply.
- IN (Input): This pin is used for high or low-level control signals to trigger the relay. For multi-channel modules, each channel will have its own 'IN' pin (e.g., IN1, IN2, etc.).
3.2 Relay Output Connections
Each relay on the module provides three output terminals for connecting your load:
- NO (Normally Open): This contact is open (disconnected) when the relay is not activated. It becomes shorted (connected) with the COM terminal when the relay is triggered.
- COM (Common): This is the common terminal for the relay switch. Connect the load's power source or the load itself to this terminal.
- NC (Normally Closed): This contact is closed (connected) with the COM terminal when the relay is not activated. It becomes open (disconnected) when the relay is triggered.
Choose the appropriate NO or NC terminal based on your application's requirements for switching behavior.
3.3 High/Low Level Trigger Selection
The module features a jumper (or jumpers for multi-channel versions) for selecting the trigger level for each relay:
- LOW Level Trigger: If the jumper is placed to short the
