Description
2 analog current outputsHART protocol integrationSupport for HART variablesElectrically isolated analog channels16-bit digital converter resolutionOSP modeNetTime timestamp: HART image
The module is equipped with 2 current outputs with 16-bit digital converter resolution. It supports the HART communication standard for data transfer, parameter configuration and diagnostics.The 2 channels are electrically isolated from each other. The user can select between the 3 output ranges 4 to 20 mA, 0 to 20 mA and 0 to 24 mA.
