GM8804C-8

GM8804C-8 Weighing indicator

The weighing indicator is a robust and adaptable indicator, designed to meet all basic weighing needs and is exceptionally versatile in building systems with PLC/PC with many options of communication ports including PROFIBUS-DP.


  • CE compliant User programmable 20 I/O ports (8 inputs and 12 outputs)
  • Full digital calibration without weights
  • Two weighing modes: Gross mode and Net mode
  • Automatic tare subtracting and tare clearing
  • Automatic accumulating
  • Patent pending two-layer advanced digital filtering algorithm
  • Communication interfaces: serial interface or analog output interface or PROFIBUS-DP interface (optional)
