p{margin-block-start: 0; margin-block-end: 0} 1. Dimensions: 50.6mm (L) * 38.8mm (W) * 19.3mm (H) 2. Weight: 30g 3. PCB Color: Black 4. Four 3.1mm diameter screw holes are located around the board for easy installation and fixing. 5. High-quality single-pole, double-throw relays. One common terminal, one normally open terminal, and one normally closed terminal. 6. Optocoupler isolation for excellent anti-interference performance. 7. Low-level pull-in, high-level release. The status indicator lights up when pulled in and turns off when released. 8. VCC is the system power supply, and JD_VCC is the relay power supply. The default relay voltage is 5V; insert a jumper cap to ensure proper operation. 9. Maximum relay output: DC 30V/10A, AC 250V/10A
