24 Bit Differential Analog to SDI-12 Interface Din Rail TBSAB03-DR

The TBSAB03-DR is a 4 differential channel analog to SDI-12 interface for 24 Bit A/D conversion of sensor signals. A/D conversion and configuration is controlled via SDI-12 commands. The interface is equipped with signal conditioning circuits which can be customized for various input voltage ranges. It offers low current consumption and comes in a Dinrail housing.

Each channel can be independently scaled with a 3 rd order polynomial to enable gain and offset calibration of the connected sensors.

The TBSAB03-DR provides digital signals for the power management of the connected sensors. Four onboard, SDI-12 controlled high side FET- switches are provided to power on/off connected sensors.
