MeteoWind and MeteoTemp RS-485 MODBUS sensor wiring function and wire colors.
ANSWER: The wire colors for the all of the RS485 MODBUS sensors are the same for all BARANI DESIGN products. MeteoTemp, MeteoWind 2, Heated MeteoWind 2 all have identical wire colors and connection to make the sensors interchangeable and installation simple.
Heated MeteoWind 2, MeteoWind 2, MeteoTemp MODBUS sensor wire colors and function:
Brown wire - Power + (5 to 24VDC) (MeteoTemp 5 to 15VDC only)
White wire - Ground - (GND)
Green wire - RS485 A (Non-inverting - some PLC/logger systems may have A & B wires reversed)
Yellow wire - RS485 B (Inverting - some PLC/logger systems may have A & B wires reversed)
MODBUS is easy and therefore simple to implement into your measurement systems.
