4 Channel Relay Module
Product introduction:
1. Relay 250V 30A
2. Size: 143*60*20 (length*width*height)
3. Input power: 5V DC (optional isolation module, AC100-250V power supply)
4. Input high level control signal voltage:
(0-1V state low level relay OFF)
(1.5-5V state high level relay ON)
Input part:
DC+: Connect to the positive pole of the power supply (power supply according to the relay voltage, if an isolation module is selected, this interface can be used for high-level trigger power supply)
DC-: Connect the negative pole of the power supply
CH1: 1 way relay module signal trigger terminal (high and low level trigger is valid (optional))
CH2: 2-way relay module signal trigger terminal (high and low level trigger is valid (optional))
CH3: 3-way relay module signal trigger terminal (high and low level trigger is valid (optional))
CH4: 4-way relay module signal trigger terminal (high and low level trigger is valid (optional))
Meaning of high level and low level:
High-level triggering refers to the fact that there is a positive voltage between the signal trigger terminal (IN) and the negative pole of the power supply. It is usually a trigger method that connects the positive pole of the power supply to the trigger terminal. When the trigger terminal has a positive voltage or reaches the trigger When the voltage is applied, the relay is closed.
Low-level triggering refers to when the voltage between the signal trigger terminal and the negative pole of the power supply is OV, or the voltage at the trigger terminal is lower than the voltage of the positive pole of the power supply. When the voltage is low enough to trigger, the relay will be closed. A trigger mode in which the negative pole of the power supply is connected to the trigger terminal, so that the relay is closed.
