Power Configuration Guide

For 5V Logic MCU (e.g., Arduino UNO):
Use a single 5V power source for both the XL9535 IC and the relays.

For 3.3V Logic MCU (e.g., ESP32, Raspberry Pi):
Use Dual Power Mode:

  • 3.3V to power the XL9535 IC

  • 5V to power the relays

Dual Power Mode improves system stability by isolating relay power from MCU power, reducing noise and ensuring reliable I2C communication.


Why Choose This Module?

  • Professionally designed and manually soldered for maximum reliability

  • Built for seamless integration into smart systems

  • Designed with installation & long-term maintenance in mind

  • Ready for DIN rail enclosure builds

  • Dual Power Mode improves system stability

Tech Spec from the manufacturer

Power Supply
In Singel Power Mode:  Input a 5V@1A power from VIN&GND1 or 5V&GND2 or Type-C USB5V    
In Dual Power Mode:     Input a 3.3-5V@0.5A power from VIN&GND1 and a 5V@1A power from 5V&GND2 or Type-C USB5V

Relay Output
The relay outputs are equivalent to 8 independent SPDT switches,as below: 
NC1-NC8: Normally close,the NC disconnect with COM when relay closed and connect with COM when relay released. 
COM1-COM8: Common end
NO1-NO8: Normally open end,the NO disconnect with COM when relay released and connect with COM when relay closed.
Control Voltage: DC30V or AC250V Max /channel
Output Current:  0-7A/channel
Output Power:   0-800W/channel
