Feature

●CH2: Signaling trigger end of relay module (high level trigger)
●Trigger is typically achieved by connecting the power electric positive end to the end of the signal trigger
●Product Description:
●Module power: power supply is DC mustiness, voltage must match relay voltage
●Triggers are usually achieved by connecting the negative end of the power source to the end of the signaling trigger

Input Power: 5VDC
Input control signal voltage:
(0 - 2.5 V, low level status is OFF relay).
(3-5V, high level state, ON relay)
Module Interface:
Input:
(DC + positive connection power supply (depending on to interfere with power voltage)
DC-Connection Power Negative
CH1: Signal trigger end of relay module (high level trigger)
CH2: Signal trigger end of relay module (high level trigger)
CH3: Signal trigger end of relay module (high level trigger)
CH4: Signal trigger end of relay module (high level trigger)
Meaning of High and Low Level:
It refers to the forward voltage between the trigger end (CH) and the power negative pole.
Triggers are typically achieved by connecting the front end of the power source to the end of the signal trigger
The relay is closed when the end of the trigger has a positive voltage or the voltage reaches the trigger point.
The relay is closed when the trigger end of the low level and the negative pole of the power supply, or the voltage at the trigger end is lower than the positive pole of the power that reaches the trigger point level.
Triggers are typically achieved by connecting the negative end of the power source to the end of the signal trigger
Product Description:
Module Power: Power supply must be DC, voltage must match relay voltage.
Wiring Method: If the signal trigger end has a low level trigger, the relay will be powered by the device and turned on.
