Description:
  • 1 ABR incremental encoder 5 V
  • Encoder input monitoring (up to 250 kHz input frequency)
  • 2 additional inputs, e.g. for latch input
  • 5 VDC, 24 VDC and GND for encoder supply
  • NetTime timestamp: Counter change

The module is equipped with 1 input for an ABR incremental encoder with RS422-based output signals and 5 V encoder supply. The encoder inputs are monitored (A, B, R, A\, B\, R\).
