User manual for the Tekbox TBSAB02/TBSAB02DR 24-bit analogue to SDI-12 interface, covering installation, calibration, and application examples for sensor…
The Tekbox TBSAB02 and TBSAB02DR are 4+1 channel analogue to SDI-12 interfaces designed for 24-bit A/D conversion of sensor signals. These devices connect sensors with voltage or current loop outputs to SDI-12 networks and feature customizable signal conditioning circuits. The interfaces are available in an IP67 rated Fibox housing or a DIN-rail housing and support independent scaling for each channel.
