Product Description<br>The default delivery for 5V relay 12V/24V relay  please contact the owner  or leave a message.<br>a relay module  with photoelectric isolation.<br>high level can be controlled. (the default control for high level up. Low level connection are as follows: remove the short cap  VCC connected to the positive pole is connected with the control end  GND  IN connected to 5V  COM termination).<br>double LED lights  LED light after power on POWER. The relay is attracted RELAY LED bright.<br>each relay can control the 250V/10A AC voltage  or 30V/10A DC voltage (current is more than 2A  please add tin  so as not to damage the PCB).<br>PCB on the back of a solder window  the user can add tin increased current control.<br>aeProduct.getSubject()<br>Module pinout:<br>1 VCC - 5V/12V/24V  visual relay and relay module is connected to the 5V voltage (5V  12V relay modules connected to the 12V voltage  24V voltage 24V relay module.<br>2 GND - ground / with the negative electrode of the power.<br>3 IN - control end  drive current should be more than 4mA.<br>4 COM - control loop wire.
