Description:
1. The module uses genuine quality relay normally open interface Maximum load: AC 250V/10A, DC 30V/10A;
2. Adopt SMD optocoupler isolation, strong driving ability and stable performance; trigger current 5mA;
3. The working voltage of the module is 5V/12V/24V;
4. The module can be set to trigger high or low by jumper;
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. Humanized interface design, all interfaces can be directly connected to terminal leads, which is very convenient
8. Module size: 51mm*25.5mm (L*W)

Module Interface:
1.DC+: Positive power supply (VCC)
2. DC-: Negative power supply (GND)

Relay Output:
1. NO: relay normally open interface
2. COM: Common Interface Relay
3. NC: relay normally closed interface

High and Low Level Trigger Options:
1. It is low-level triggered when the jumper is connected to the LOW pin
2. It is HIGH triggered when the jumper is connected to the HIGH pin
