Emonhub Modbus RTU Interface for E+E sensors

These are the default modbus setting for these sensors. The Modbus settings can be changed using the E+E PCS10 config utility (Windows only)

Pinout sensor cable (195271) HA010832:

  • Gray VCC (10-29V DC)

  • Green GND

  • Brown Modbus D-

  • Yellow Modbus D+

  • White N/C
