Description
8-channel 5V 10A relay module with low/high-level control LL/HL for Arduino, ESP8266, ESP32, and Raspberry Pi
This 8-channel relay module with optoisolation is designed for electronic projects and microcontroller systems. 5V supply voltage ensures compatibility with most popular platforms. The relays support current up to 10A at 250V AC or 30V DC, enabling safe switching of high-power loads.
Key technical features
- Supply voltage: 5V
- Control voltage: 5V (a 3.3V signal is sufficient to change state)
- Control type: HL/LL - each channel can be set to high or low level control independently
- Maximum load: 10A 250V AC / 10A 30V DC
- Number of channels: 8 independent relays
- Status indication: built-in LEDs for each channel
- Physical dimensions: 138 mm x 50 mm x 20 mm
Benefits
- Circuit safety: built-in optoisolation effectively protects control circuits from damage caused by voltage spikes.
- Easy installation: terminal block connectors allow quick and secure wire attachment without soldering.
- Flexible configuration: individual high- or low-level control per channel using jumpers.
- Easy diagnostics: LEDs indicate each relay’s state in real time, simplifying system monitoring.
- High current capability: direct switching of high-power loads up to 10A.
Example applications
- Lighting control in smart building systems.
- Switching home appliances from a microcontroller.
- Home and industrial automation projects.
- Security and access control systems.
- Advanced prototyping projects requiring galvanic isolation.
The module is a versatile and reliable actuator, suitable for both professional installations and advanced electronic projects.
