Module interface:

Input section:

DC+: power supply (by relay voltage) DC-: negative power source CH1: 1 relay module signal trigger (active low) CH2: 2 relay module signal trigger (active low) CH3: 3 relay module signal trigger (active low) CH4: 4 relay module signal trigger (active low) CH5: 5 relay module signal trigger (active low) CH6: 6 relay module signal trigger (active low) CH7: 7 relay module signal trigger (active low) CH8: 8 relay module signal trigger (active low)

High level and low level meaning:

The high level trigger refers to the signal trigger end (in) and the negative electrode of the power between a forward voltage, usually with the anode of the power supply and trigger end connected to a trigger mode, when the trigger end of a positive voltage or voltage reaches the trigger relay is attracted. Low level trigger refers to the signal triggering between the end and the negative electrode of the power supply voltage is ov, or to say the trigger voltage lower than the positive power supply voltage, low to can trigger voltage, the relay, usually is the negative terminal of the power supply and trigger end connected a trigger mode, so that the relay is attracted.
