1 Channel 12V Relay Module 30A With Optocoupler Isolation Support High And Low Level Trigger BESTEP for Arduino - produc

Description The module adopts high quality 30A relay and the maximum load is normally open interface AC 250V 30A DC 30V 30A The chip optocoupler isolation strong driving ability stable performance trigger current 5mA Module working voltage 12VCan be set up by high jumper or low level trigger Fault tolerant design the relay will not operate even if the control line is disconnected Power indicator green relay status indicator red The interface design is humanized all interfaces can be directly connected through the terminals so it is very convenient Module size 50mm x 33mm x 24mm length width height Product net weight 36gThere are 4 fixed bolt holes holes 3 1mm spacing 44 5mm x 27 5mmRelay version 12VQuiescent current 5mAMaximum current 190mATrigger current 2 4mA Module interface description 1 DC module DC power supply positive pole trigger terminal voltage positive 2 DC module DC supply negative pole trigger terminal voltage negative 3 IN signal trigger terminal default trigger voltage is the same as power supply 4 JD relay control terminal voltage positive pole5 JD relay control terminal voltage negative pole6 DC and JD uses jumper cap short connection trigger terminal and relay control terminal voltage is the same 7 Selection of high and low level trigger mode when jumper is connected to L terminal IN terminal is low level trigger and H terminal is high level trigger 8 Normally closed terminal NC relay normal
