Module Interface Description: Input part:
· DC+: Connect to the positive power supply (according to the relay voltage)
· DC-: Connect to the negative power supply
· CH1: 1 relay module signal trigger terminal (low-level trigger effective)
· CH2: 2 relay module signal trigger terminal (low-level trigger effective)
Meaning of High and Low Levels:
· High-level trigger refers to a positive voltage between the signal trigger terminal (IN) and the negative power supply, usually connected to the positive power supply. When the trigger terminal has a positive voltage or reaches the trigger voltage, the relay is activated.
· Low-level trigger refers to a voltage of 0V between the signal trigger terminal and the negative power supply, or a voltage lower than the positive power supply, low enough to trigger the relay. This usually involves connecting the negative power supply to the trigger terminal to activate the relay.
Product Usage Instructions:
1. Power Supply for the Module: The power supply must be DC, and the voltage must match the relay voltage.
