Description:
  • 2 analog current measurement inputs
  • Electrically isolated analog channels
  • Electrically isolated sensor supplies
  • 16-bit digital converter resolution
  • NetTime timestamp: Moment of measurement

The module is equipped with 2 current measurement inputs with 16-bit digital converter resolution.

Each current measurement input has its own sensor supply. The two channels with their respective sensor supplies are electrically isolated from each other. The user can select between the two measurement ranges 4 to 20 mA and 0 to 25 mA.
