Specification: Item Type: Relay Module Material: PCB Relay: 250V 30A Product Size: Approx. 143 x 60 x 20mm / 5.63 x 2.36 x 0.79in (L x W x H) Input Power Supply: 5V DC (optional isolation module, AC100-250V power supply) Input High Level Control Signal Voltage: (0-1V low level relay OFF) (1.5-5V status high level relay ON) Input Part: DC+: Connected to the positive pole of the power supply (power is supplied according to the relay voltage. If the isolation module is selected, this interface can be used for high-level trigger power supply) DC-: Connected to the negative pole of power supply CH1: 1 channel relay module signal trigger terminal (high and low level trigger is valid (optional)) CH2: 2 channel relay module signal trigger terminal (high and low level trigger is valid (optional)) CH3: 3 channel relay module signal trigger terminal (high and low level trigger is valid (optional)) CH4: 4 channel relay module signal trigger terminal (high and low level trigger is valid (optional)) Meaning of High Level and Low Level: High level trigger means that there is a positive voltage between the signal trigger terminal (IN) and the negative pole of the power supply. Usually, the positive pole of the power supply is connected to the trigger terminal. When the trigger terminal has positive voltage or reaches the trigger voltage, the relay is closed. Low level trigger refers to the trigger when the voltage between the signal trigger terminal and the negative pole of the power supply is OV, or the trigger terminal voltage is lower than the positive pole voltage of the power supply. When the voltage is low enough to trigger, the relay will close. A trigger mode, wherein the negative pole of the power supply contacts the originator to close the relay.
