DIYUSER 5V 1 2 4 8 Channel SSR G3MB-202P Solid State Relay Module 240V 2A Output with Resistive Fuse Diy Kit For ARDUINO

DC +: Connect the power supply positive (according to the relay voltage)

DC-: Connect the power supply negative

CH1: 1 relay module signal trigger terminal (low level trigger active)

CH2: 2 relay module signal trigger terminal (low level trigger active)

CH3: 2 relay module signal trigger terminal (low level trigger active)

CH4: 2 relay module signal trigger terminal (low level trigger active)

High-level trigger refers to the signal trigger side (IN) and the negative power supply has a positive voltage between the positive and the power supply is usually connected to the trigger side of a trigger, when the trigger side voltage or trigger to reach the trigger Voltage, the relay is pull.

Low-level trigger refers to the voltage between the signal trigger terminal and the negative terminal of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive terminal of the power supply. When the voltage is low enough to trigger, the relay is pulled in, The negative side of the power supply is connected to the trigger side of a trigger, so that the relay is pull.

Voltage Version Quiescent Current Operating Current Trigger Voltage Trigger Current

1 channel 5V 0mA 12.5mA 0-2.5V 2mA

2 5V 0mA 22.5mA 0-2.5V 2mA

4 5V 0mA 48mA 0-2.5V 2mA

4 5V 0mA 102mA 0-2.5V 2mA

1. Module power supply: the power must be DC, the voltage and the relay voltage to match

2. Wiring method:

When the trigger side of the signal trigger level, the relay will be connected, the device has electricity and work

Precautions:1. Module power supply: power must be DC, 5V power supply2. Module control terminal voltage: This module can only be used to control the AC current, can not control the DC current.
