NC (Normally Closed) means it is closed when not triggered. COM is the common terminal. When you apply an active low signal, the relay switches: NO connects to COM, and NC disconnects from COM.\n\u003c\/p\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat payment options are available for the 5V Dual Channel Relay Module?\u003c\/summary\u003e\n\u003cp\u003eYou can pay using UPI, debit\/credit cards, or Cash on Delivery (COD).
