Electronic display MA50

Analog, length and angle measurement

Freely programmable 4-digit measurement display. The measurement information obtained from absolute sensors with analog signal output can be directly evaluated. The display features numerous individual setting options.

Profile MA50:

  • LED display (1 line of 4 digits)
  • Voltage, current and resistor inputs for length and angle measurement
  • Free programming via front keyboard
  • Non-volatile parameter storage (EEPROM)
  • 2 switching outputs (limit-dependent, programmable)
  • Compact design
