• Suitable for all strain-gauge load cells 
  • Up to 6 load cells can be connected
  • Serves as the interface between load cells and PC which have an analogue input. 
  • Two analogue outputs (0 -20 mA oder 0 - 10 V)
  • Dip switches for easy adjustment to required weighing range and for tare compensation (not via potentiometer).
