- ICStation 1CH 3V 3.3V relay power switch module with optocoupler high level trigger for ESP8266 development board. 【Optocoupler Isolation】it can control high current load via low current, and replace mechanical switch.
- Use the classical and beautiful black PCB and metal components, looks cool and pleasure to the eyes, which will show your whole DIY project superior. 2pcs with the independent anti-static packing. Size: 50x26x17mm/1.97x1.02x0.67inch, Voltage: 3V-3.3V, Current: <200mA (operating); <5mA (trigger). Operating Temperature: -25~85 Celsius.
- 【Load Capacity】7A, 240V AC; 10A 120V AC; 10A 28V DC. Please do not go beyond the voltage or current, or it will burn the relay contact. Load wire is fenestrate processed, if it is tin plated, it can bear high current (please pay attention to the insulation).
- 【Interface】 Input: VCC, GND, IN; Load Port: Normal Close, Common, Normal Open. 【Wiring】(1) VCC connects DC 3.3V positive; (2) GND connects DC 3.3V negative; (3) IN connects main control equipment input port, such as MCU, sensor output port (0 and 1, you can adjust via the switch on your own); (4) Please note that the power cannot be reversely connected, or it will burn the module.
- Connect the power; when push the switch to L, IN port will input low level, and relay will operate, S lamp will be on. If COM and NO are connected; when input high level, the relay will release, and S lamp will be off. If COM and NO are disconnected, it becomes connection between COM and NC. If push the switch to H, and not use the relay, NC and COM are connected.
