8 Channel Electromagnetic Relay Module with I2C Interface
compatible with Home Assistant / ESPHome
- PCB board dimension 72mm x 150mm
- Compatible with DIN rail plastic holder
- Operation DC voltage – 3.3V and 5.0V
- Maximum current @5.0V – 700mA
- Maximum current per relay – 10A peak
- LEDs indicators for each electromagnetic relay channel
- Relays with SPDT switch contacts: Normally Open, Common, Normally Closed
- 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 750 VAC, 50/60Hz between contact
- Relay dielectric strength 1,500 VAC, 50/60Hz between all elements
- Relay expected life Mechanical - 10,000,000 operations min.
- Relay expected life Electrical - 100,000 operations min. at rated load
- Working temperature range - 25 C ~ + 80 C
- Comes with different slave address 0x27 or 0x3F, depends on the batch
- Each board can be assigned an I2C address between 0x20...0x27 (0x38...0x3F) by the DIP switch
- The module contains an PCF8574 or PCF8574A chip
- 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.
- Up to 8 boards can be connected to I2C bus line.
