Description
Analog to SDI-12 interface TBSAB02 – 4+1 channel 24 bit A/D conversion
4+1 channel 24 bit Analog to SDI-12 interface TBSAB02 from Tekbox is a 4 + 1 channel interface for 24 bit A/D conversion of sensor signals. A/D conversion and configuration are controlled via SDI-12 commands. The device is equipped with signal conditioning circuitry that can be adapted to different input voltage ranges. It offers low power consumption and is supplied in a Fibox PC081206 IP67 rated or Din Rail housing.
Each channel can be scaled independently of each other with a 3rd order polynomial to enable gain and offset calibration of the connected sensors.
A built-in 3-wire interface for direct connection of PT100 / PT1000 provides additional versatility.
The TBSAB02 provides digital signals for power control of the connected sensors. Four built-in, SDI-12 controlled high-side FET switches are provided to turn on/off connected sensors.
