Modul Relay 3.3V 3V 1 / 2 Channel Dual Input High Low Trigger Relay Module 1CH 2CH for ESP8266 ESP32

Module description:
1. Normally open interface 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
4. Each channel of the module can be triggered by jumping wire to set high level or low level;
5. Fault-tolerant design, even if the control line is broken, the relay will not act;
6. Power indicator (green), 4-way relay status indicator (red)
7. User-friendly interface design, all interfaces can be directly connected through the terminal block, which is convenient

Module interface:
1. DC+: connected to the positive pole of the power supply (voltage according to the relay 5V).
2. DC-: connect the negative pole of the power supply
3. IN1-IN4: according to the setting of each channel, the corresponding relay can be controlled at high or low level, and the output of the relay interfaces can be directly connected to lead out, which is convenient for users to use

High and low level trigger selector:
S1-S4 is the high and low level trigger selection of relay 1-4 channels in turn;
When the COM is shorted with the low, the corresponding relay is triggered at a low level, and When the COM is shorted with the high end, it is triggered at a high level
