5V 2 Channel Relay Module

Description 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 double optocoupler isolation, strong drive capability, stable performance; trigger current 5mA; 3. The module operating voltage is 5V; 4. Each channel of the module can be triggered by jumper high or low level; 5. Fault-tolerant design, even if the control line is broken, the relay will not move; 6. Power indicator (green), 2 relay status indicators (red) 7. 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 relay 5V) 2. DC-: Connect to the negative pole of the power supply 3. IN1-IN2: According to the setting of each channel, the corresponding relay can be controlled by high or low level. Relay output: 1. NO1-NO2: Normal open interface of the relay. Before the relay is closed, it is left unconnected. After picking up, it is shorted to COM. 2. COM1-COM2: Relay Common Interface 3. NC1-NC2: Normally closed relay interface. Before the relay is closed, it is short-circuited with COM. High and low level trigger selection: 1. S1-S2 is the high and low level trigger selection for Relay 1 – 2; 2. When com is shorted to low, the corresponding relay is a low level trigger. When com is shorted to high, it is a high level trigger.
