5V 1 2 4 Channel SSR High Level Solid State Relay Module 250V 2A For Arduino Electronic components

Product Description:

1. 5V solid state relay 240V 2A, output with resistive fuse 240V 2A.

2. Size: 25*34*25 (length*width*height) Net weight: 13g

3. Input power: 5V DC (160MA)

4. Input control signal voltage: (O-1.5V state low level relay ON) (2.5-5V state high level relay OFF)

5. It is more convenient to connect the blue KF301 terminal to the control line.

Input section:

DC+: connect to the positive pole of the power supply (power supply according to the relay voltage)

DC-: connect to the negative pole of the power supply

CH: Relay module signal trigger terminal (low level trigger is valid)

High level and low level meaning:

High-level triggering means that there is a positive voltage between the signal trigger terminal (IN) and the negative pole of the power supply. It is usually a triggering method in which the positive pole of the power supply is connected to the trigger terminal. When the trigger terminal has a positive voltage

When the voltage is reached or the trigger voltage is reached, the relay is pulled in. Low-level triggering means that when the voltage between the signal trigger terminal and the negative pole of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive pole of the power supply, when the voltage is low enough to be triggered, the relay is pulled in, usually by turning it on. A trigger method in which the negative pole of the power supply is connected to the trigger terminal, so that the relay is pulled in.
