Analog to SDI-12 Interface Module TBS02B


Analog to SDI-12 Interface Module TBS02B


The TBS02B SDI-12 to ANALOG module is a SDI-12 interface for A/D conversion of sensor signals. A/D conversion and configuration of TBS02B is controlled by SDI-12 commands. The module is plug and play, targeting cost sensitive sensor applications. It offers low current consumption, small footprint and easy integration into sensor products which require a SDI-12 interface.
The user does not need to invest any time for the implementation of the SDI-12 protocol and interface hardware, as this is an integral part of the SDI-12 / ANALOG interface module.
The TBS02B contains all the necessary components for a complete SDI-12 sensor interface. It includes SDI-12 front-end, controller, crystal and passive components.
TBS02B has been engineered specifically for applications where cost, performance, time to market and ease of integration are prime considerations.
