X20cAI2438Descripción:
- 2 analog current measurement inputs
- Integrated HART protocol
- Supports HART variables
- Electrically isolated analog channels
- Electrically isolated sensor supplies
- 16-bit digital converter resolution
- NetTime timestamp: Moment of measurement, HART image
The module is equipped with 2 current measurement inputs with 16-bit digital converter resolution. It supports the HART communication standard for data transfer, parameter configuration and diagnostics.
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.
