Module interface:

1, DC+: Connect to the power supply positive pole (Voltage according to relay requirements, 12V)
2. DC-: Connect power negative
3. IN: Relay suction can be controlled at high or low level
Relay output:
1, NO: Relay usually opens interface, relay hangs up before suction, and connects with COM shortly after suction
2. COM: Relay Public Interface
3. NC: Relay normally closed interface, short connection with COM before relay suction, hanging after suction
High and low level trigger selector:

Module description:

1. The module adopts genuine high-quality relay, and the normally open interface is large load: AC 250V / 10A, DC 30V / 10A;
2. It adopts chip optocoupler isolation, which has strong driving ability and stable performance, and the trigger current is 5mA;
3. The working voltage of the module is 12V;
4. The module can set high level or low level trigger through jumper;
5. Fault tolerant design, even if the control line is broken, the relay will not act;
6. Power indicator (green), relay status indicator (red)
7. The interface design is humanized, all interfaces can be directly connected through the terminal, which is very convenient
8. Module size: 50mm * 26mm * 18.5mm (L * w * h)
9. There are 4 fixing bolt holes, holes 3.1mm, spacing 44.5mm * 20.5mm
