8 Channel Electromagnetic Relay Module with I2C Interface
- PCB board dimension 72mm x 150mm
- Relay contact resistance 100 milliohms max. ( initial value )
- Relay insulation resistance 100 MOhm min. (DC 500V)
- Relay operation time 8 ms max
- Relay release time 5ms max
- Relay dielectric strength 1,500 VAC, 50/60Hz between all elements
- Each board can be assigned an I2C address between 0x20...0x27 (0x38...0x3F) by the DIP switch
- The logic power supply voltage should match the voltage levels on the I2C bus. The SDA and SCL lines are pulled up to VDD with 5.6k resistors on the relay module.
