Giới thiệu Mô đun rơ le 2 kênh DC 12V H/L chuyên dụng cho Arduino tại Lotte Market

Module description:
1. The module adopts high-quality relays, normally open interface load: AC 250V/10A, DC 30V/10A;
2. Adopt SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;
3. The working voltage of the module is 12V;
4. The module can be triggered by jumpers to set high or low level;
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 humane, all interfaces can be directly connected through the terminal block, which is very convenient
8. Module size: 50mm * 41mm* 18.5mm (length * width * height)
9. There are 4 fixing bolt holes, the hole is 3.1mm, the spacing is 44.5mm*35.5mm

Module interface:
1. DC+: connect to the positive pole of the power supply (the voltage is according to the requirements of the relay, there are 5V.9V.12V and 24V options)
2. DC-: Connect to the negative pole of the power supply
3. IN1: 1 signal trigger terminal, you can set high or low level to control the relay to close
3. IN2: 2-way signal trigger terminal, you can set high or low level to control the relay to close

Relay output:
1. NO1: 1 relay normally open interface, the relay is suspended before being closed, and shorted to COM1 after being closed
2. COM1: 1 relay common interface
3. NC1: 1-way relay normally closed interface, short-circuited with COM1 before the relay is closed, and suspended after being closed
4. NO2: 2-way relay normally open interface, the relay is suspended before closing, and shorted to COM2 after closing
5. COM2: 2 relay common interface
6. NC2: 2-way relay normally closed interface, short-circuit with COM2 before the relay is closed, and hang in the air after being closed

High and low level trigger selection terminal:
1.S1 is the high and low level trigger selection of 1 relay;
2.S2 is the high and low level trigger selection of 2 relays;
3. When com and low are shorted, the corresponding relay is triggered at low level, and when com is shorted with high, it is triggered at high level.
