Description:
1. Maximum Load: AC 250V/10A, DC 30V/10A
2. Isolated by SMT optocoupler, strong driving ability, stable performance
3. Operating Voltage: 5V
4. Can be set through the jumper high level or low level trigger
5. Fault-tolerant design, even if the control line is broken, the relay will not operate
6. Power indicator (green), relay status indicator (red)
7. All interfaces can be directly connected through the terminal leads, very convenient
8. Size: 50mm * 26mm * 18.5mm (L * W * H)
9. With 4 fixed bolt holes, hole 3.1mm, spacing 44.5mm * 20.5mm

Relay Inputs:
1. DC+: Connected to the positive terminal
2. DC-: Connected to the negative terminal
3. IN: High or low level control relay

Relay Outputs:
1. NO: Pull forward and backward vacant relay short with COM
2. COM: Common interface
3. NC: Relay front shorted to COM, back pulled empty

High and low level trigger selection terminal:
1. When jumper is shorted to LOW, it is triggered by low level
2. High level trigger when jumper is shorted to HIGH
