Switching outputs

For tasks in automation

  • Zero crossover; trigger points 1 and 2
  • Sorting signals “<” and “>”
  • Error

Switching inputs

For tasks in automation

  • Zero reset, preset
  • Cross over reference point and ignore reference signals
  • Measured value output or display freeze
  • Start measurement series
  • Minimum/maximum/difference display
  • Gating of the two encoder inputs
  • Sum or difference display

Power connection

100 to 240 V AC (-15 % to +10 %), 48 Hz to 62 Hz; 30 W

Operating temperature

0 °C to 50 °C (storage temperature –40 °C to 85 °C)

Weight

2.5 kg

1) Purely serial, no evaluation of the incremental signals

2) Depends on the signal period of the connected encoder (display step  signal period/4096)
