英文描述：

Module parameters:

1. Size: 50.5mm (length) * 38.5mm (width) * 18.5 (height)
2. Weight: 31g
3.PCB color: black
4. There are 4 fixing screw holes around the board, the hole diameter is 3.1mm, which is convenient for installation and fixing.
5. The relay uses high quality Songle relay, single pole double throw. a common end, a normally open end, and a normally closed end
6. Optocoupler isolation, good anti-interference
7. Low level pull-in, high level release. The status indicator is on when the inverter is closed, and the status indicator is off when released.
8. VCC is the system power supply, and JD_VCC is the relay power supply. Plug in the jumper cap
 
Electrical parameters:

Supply voltage: 5VDC
Current: greater than 100mA
Load: 250V 10A AC or 30V 10A DC
 
Wiring instructions:

VCC: system power supply positive
GND: system power supply negative
IN1--IN2: Relay Control Port
(Do not reverse, causing the module to burn out and we will not return it.)
