There are 4 fixing screw holes around the board, the hole diameter is 3.1mm, which is convenient for installation and fixing. The relay uses high quality Songle relay, single pole double throw. a common end, a normally open end, and a normally closed end. Optocoupler isolation, good anti-interference. 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. VCC is the system power supply, and JD_VCC is the relay power supply.
