      Overview Manuals Common Applications Product Precautions
      6ES7231-4HF32-0XB0 provides eight differential analog inputs for a Siemens SIMATIC S7-1200 station.
      • Provides eight differential analog input channels
      • Accepts voltage ranges up to ±10 V
      • Accepts 0–20 mA and 4–20 mA current inputs
      • Uses 12-bit-plus-sign / 13-bit ADC conversion

      The SM 1231 module is installed in an S7-1200 rack with its documented sensor wiring and TIA Portal configuration. Commissioning verifies the slot identity, range selection, 24 V supply, analog commons and individual input response.

      Important Notice: Confirm 6ES7231-4HF32-0XB0, Siemens SIMATIC S7-1200 host, slot, SM 1231 channel map, voltage/current ranges, 24 V supply, analog commons, shields, TIA Portal configuration and controlled eight-channel test results before commissioning.
