Description:
  • 2 analog inputs
  • Current or voltage signal configuration for the entire module
  • 16-bit digital converter resolution
  • Minimum conversion time of 40 µs for all inputs
  • The conversion time for the entire module can be configured in 0.02 µs steps.
  • Maximum 14 samples (16-bit) for the entire module per X2X Link cycle
  • Oversampling: Up to 16 analog values per channel (internal)
  • Timestamp for the last conversion of an X2X Link cycle

The module is equipped with 2 inputs with 16-bit digital converter resolution. It is possible to select between the current and voltage signal using different terminals. With the oversampling function, up to 16 analog values per channel can be recorded.

This module is designed for X20 6-pin terminal blocks. If needed (e.g. for logistical reasons), the 12-pin terminal block can also be used.
