LT80 Clear and easy to use HMI functions

  • 7-inch touch screen LCD display
  • Multiple measurement modes (current value, MIN, MAX P-P, ADD/SUB.) Can be used for defective part identification, trend management, part sorting and tolerance judgement by using 2 or 4 state comparator function
  • Displays I/O status
  • Three data storage and parameter setting options (SD card, USB, and Ethernet)
  • Multiligual support (Japanese, English, German)

MG80 Expandable multi-axis measurement module system

  • Connect up to 32 Magnescale DK- or DT-series gauges (via MT adaptor)
  • DIN rail mount for easy installation (MG80 and LZ80)
  • High speed latch (via MG80-LM latch module)
    • -Synchronized angle and position measurement is available*1 by connecting a linear or rotary encoder*2
    • *1 16 axes max.
    • *2 Requires A/B Quadrature encoder signal (EIA-422 compliant).
    • -Latching data with specific angles or distances can be saved to the LT80.

LZ80 I/O module

  • Equipped with 8 inputs and 8 outputs
  • Functions can be assigned freely from LT80
  • Up to two MG80 I/O modules can be connected to one MG80-MA
