1 Channel DC5V Solid State Relay Module AC240V 2A Low Level Trigger Relay Board Relais Module

1. Size: Approx. 34mm x 25mm x 21.5mm

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

3. Input control signal voltage:

(0-1.5V state low level relay ON)

(2.5-5V state high level relay OFF)

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

Voltage version: 5V

Static current: 0mA

Working current: 12.5mA

Trigger voltage: 3.3-5V

Trigger current: 2mA

NOTE: The power supply must be DC Voltage, and the voltage must be consistent with the relay voltage

Input section:

DC +: positive power supply (by relay voltage power supply)

DC -: connect power negative

CH: relay module signal to trigger the end (low to trigger effective)

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 trigger 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. A trigger mode in which the negative pole of the power supply is connected to the trigger terminal, so that the relay is closed.
