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.Specifications Differential analog to SDI-12 interface 4 24 Bit Sigma Delta ADC channels 4 analog differential inputs; configurable as 4-20mA current loop or 0-2,5V voltage inputs; other voltage ranges upon order Input over-voltage protection Configurable 12V warm up and power-off time for each channel
