relayNote: We will send according to the voltage you choose to place the order. Don't worry too much about the voltage of the picture and the voltage of the order you placed.Module parameters:1. Size: 75mm (length) * 55mm (width) * 19.3mm (height)2. Weight: 61g3.PCB color: blue4. There are 4 fixing screw holes around the board, the diameter of the hole is 3.1mm, which is convenient for installation and fixing.5. The relay uses high-quality relay, single pole double throw. One common end, one normally open end, one normally closed end6. Optocoupler isolation, good anti-interference7. Low level pull-in, high level release. The status indicator is on when it is closed, and it is off when it is released.8. VCC is the system power and JD_VCC is the relay power. 5V relay is issued by default, just plug in the jumper cap9. Maximum relay output: DC 30V / 10A, AC 250V / 10AWiring instructions:VCC: system power positiveGND: system power negativeIN1--IN4: relay control port
