2-Channel-RS485-Sensor-Interface with freely available Configuration and Evaluation Software VS2. The Evaluation and Excitation of the connected Sensor occurs via the RS485 Interface. Sensors with Output Signals of mV/V, ±5V, ±10V or 0/4 … 20 mA are suitable for the Connec­tion. Through the Measuring Rate of up to 2500/s, high-dynamic Measurements are realizable. This Measuring Amplifier is also very suitable for heavy Industry Applications by its robust Alu­minum Die Cast Housing.

The sensor interface SI-RS485 is connected between the sensor and the PC. By this, analog sensor signals with up to 16 bit resolu- tion are digitized.
Highly-dynamic are realizable with a measuring rate of 2500 measurements/sec per measurement channel. The measured values are transferred to a PC via the RS485 interface and are visualized through the software.
If a control signal is integrated in the sensor, an automatic adjustment can be carried out, which is checkable at any time (monitoring of the measuring chain).
Many commercially available sensors such as force-, torque-, displacement- or pressure sensors can be used with the SI-RS485. The sensor parameters can be stored in the SI-RS485. After a one-time parameterization each sensor is automatically recognized by the software.
The voltage supply of the SI-RS485 occurs via an external power supply unit. Through the measuring amplifier, the connected sensors are being directly supplied with voltage directly, whereby a separate voltage of the sensors has been omitted.
Unwanted frequencies are filtered with the second-order low-pass filter. Here, a differentiation between 4 limit frequencies is possible. The connection to LabVIEW or the integration into internal programs is possible with the freely available driver package.
