5-30V 10A Wide Voltage Trigger Delay Relay Module Timer Module Two Trigger Modes

Description Time can be adjusted by a potentiometer to meet the use of most of your occasions With Micro USB 5 0V power supply input it is very convenient to use 5 30V ultra wide power supply voltage Two trigger modes external trigger and onboard buttons trigger It has a relay suction indicator Strong anti interference ability all kinds of interference under the relay will not be misoperation suitable for industrial control Module features 1 Working voltage 5 30V wide voltage two kinds of power supply interfaces MicroUSB and welding terminals 2 Working mode after the module is powered the output state of the module is as follows normally open NO and public terminal COM and normally closed NC is connected with the public terminal COM In the external contact TRIG to start a low pulse signal or touch the trigger button instantly the relay and the indicator light the relay output state is normally open NO and the common end COM conduction normally closed NC and the common end COM fault open after 0 24 seconds this time can be adjusted according to your needs minutes after the relay is switched off the relay back to the state before the trigger 3 Time can be adjusted by the potentiometer and the default is 0 24 seconds If it takes longer a larger capacitor C2 or a potentiometer can be replaced by itself The time delay formula T 1 1RC For example the capacitance 22uF resistance 1M is T 1 1 0 000022 1000000 24 2 seconds 4 Has a rel
