Connectivity and flexible integration of our high-accuracy and high-speed I/O modules into any automation system is in our DNA. That is why we have made our high-performance Q.series X I/O modules available for easy and comfortable integration into TwinCAT, the EtherCAT master from Beckhoff.
Because EtherCAT was developed with industrial automation in mind, finding high-accuracy data acquisition devices that cover a wide-range of sensors can be a challenging exercise. Modern data acquisition system vendors like Gantner Instruments offer a full range of measurement modules with a direct EtherCAT interface. There is no limitation in the type of sensor with an EtherCAT-based data acquisition system: thermocouple, Pt100, LVDT, strain gage, IEPE/ICP©, piezoelectric (charge), high-voltage measurement up to 1200 VDC, and even fiber Bragg grating sensors.
We provide robust I/O modules with best-in-class accuracy, highest stability, and very low noise and long-term drift for all these measurements. What do we mean by best-in-class accuracy? Here are three examples:
- The margin of error for our A105 I/O module with 4 channels for RTD measurements is 0.05 K at a resolution of 100 µK.
- Our A108 I/O module provides 8 channels for voltage or current measurement and has an error margin of +/-2 mV for an input range of +/-10 V with a resolution of 1.5 µV.
- Our A116 I/O module with 8 inputs for quarter-, half-, and full-bridge strain gage circuits has a gain accuracy of 0.05 %.
