Module description:
1. The module adopts genuine quality relay, the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A;
2. Using optocoupler isolation, strong drive capability, stable performance; trigger current 5mA;
3. Each channel of the module can be triggered by jumper high or low level;
4. Fault-tolerant design, even if the control line is broken, the relay will not move;
5. Power indicator (green), 1 relay status indicators (red)
6. User-friendly interface design, all interfaces can be directly connected through the wiring terminals, very convenient
Module interface:
1. DC+: Connect to the positive pole of the power supply (voltage is relay 5V)
2. DC-: Connect to the negative pole of the power supply
3 .IN: The relay can be controlled by high or low level
Relay output:
1. NO: Relay normally open interface, before the relay is vacant, it will be shorted to COM after picking up
2. COM: Relay Common Interface
3. NC: Normally closed relay interface. Before the relay is closed, it is short-circuited with COM.
High and low level trigger selection:
1. H & L is the high and low level jumper trigger selection of relay 1;
