Description
16-channel relay module for Arduino, ESP32, ESP8266 and Raspberry Pi
Module equipped with 16 relays, controlled by a low state (0V) applied to the input connector. Enables safe control of devices drawing up to 10A directly from microcontroller pins. High operating safety is ensured by built-in opto-isolation, which physically separates the control signal from the circuit powering the relay coils. For correct operation, only coil power and a digital control signal need to be connected.
Key technical specifications
- Number of relays: 16
- Supply voltage (VCC): 12V
- Control signal: activated by low state
- Input current draw: approximately 60mA per channel
- Maximum load: 10A at 250V AC and 10A at 30V DC
- Control connectors: 16 goldpin inputs
- Protection: full opto-isolation of circuits
- State indication: 16 LEDs indicating activation
- Unit mass: 225g
- Physical dimensions: 180×90 mm
Example applications
- Multi-point lighting control in building automation systems
- Switching actuator circuits in industrial projects
- Controlling motors, solenoid valves and low-power pumps
- Expanding alarm systems and access control setups
- Building advanced IoT projects with popular microcontrollers
Benefits
- Simultaneous control of up to 16 independent electrical circuits
- High microcontroller protection thanks to hardware opto-isolation
- Full compatibility with Arduino, ESP8266, ESP32 and Raspberry Pi platforms
- Easy monitoring of each channel’s state via built-in LED indicators
- Simple mounting and quick connection using standard goldpin connectors
