API

relay4_0.get_adc_12bit_value(0)

• Retrieves the 12-bit ADC raw value, returning an integer ranging from 0 to 4095. This is the unprocessed voltage data read from the specified module's ADC.

relay4_0.get_adc_12bit_value(1)

• Retrieves the voltage value from the 12-bit ADC, returning a voltage value ranging from 0 to 26 volts.

relay4_0.get_adc_8bit_value(0)

• Retrieves the 8-bit ADC raw value, returning an integer ranging from 0 to 255. This is the unprocessed voltage data read from the specified module's ADC.

relay4_0.get_adc_8bit_value(1)

• Retrieves the voltage value from the 8-bit ADC, returning a voltage value ranging from 0 to 26 volts.

relay4_0.get_relay_status(1)

• Retrieves the status of the relay module, returning a value of 0 or 1.

relay4.init_i2c_address(0x26)

• Initializes the I2C address of the device.

relay4_0.set_all_relay_state(1)

• Sets the state of all relays.

relay4_0.set_i2c_address(0x26)

• Sets the I2C slave address of the device.

relay4_0.set_relay_state(1, 1)

• Sets the state of relay 1.
  • Parameter 1: Relay number (1-4)
  • Parameter 2: "ON" to close the relay, "OFF" to open the relay.
