TBSAB02
4+1 CHANNEL 24 Bit Analogue To SDI-12 Interface
The TBSAB02 is a 4+1 channel analogue 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 Fibox PC081206 IP67 rated or in Din Rail housing.
