Versatile Input Channels with Programmable Sensor Supply

Q-series-X-A107-4xLemo2B-SV

The Q.series X A107 4 x Lemo 2B SV module is equipped with four universal analog input channels, each capable of measuring a variety of signals, including voltage, current, resistance, RTD, and strain gage. It distinguishes itself with a programmable sensor supply for each channel, offering a supply voltage range from 3.3 V to 20 V (or up to 24 V if the supply voltage is greater than 27.3 V) in steps of 10 mV and a current limit ranging from 50 mA to 100 mA in increments of 100 µA.

Simplifying Sensor Integration with Advanced Sensor Supply

The Q.series X A107 module includes a versatile sensor supply suitable for a variety of active sensors such as pressure transducers, amplified load cells, and accelerometers. The integrated sensor supply eliminates the necessity for external power sources, ensuring that sensors receive adequate power directly from the DAQ system. This innovation simplifies the setup process, reduces wiring intricacies, and minimizes connection points, which, in turn, helps mitigate potential noise interference during data acquisition.

High-Resolution Data Acquisition and Signal Processing

The module’s precision is enhanced by a high-accuracy 24-bit ADC and a sample rate of 20 kS/s per channel, ensuring that each measurement is captured with high resolution and detail. The module’s signal conditioning capabilities, including linearization, filtering, averaging, and RMS calculation, allow for tailored signal processing that meets the specific requirements of complex engineering applications.

Galvanic Isolation for System Integrity

To ensure the protection of sensitive measurement equipment, the A107 4 x Lemo 2B SV provides 3-way galvanic isolation of 500 VDC between channels, power supply, and bus system, safeguarding against electrical noise and enhancing the integrity and reliability of the measurement data.

Robust Design for Demanding Environments

Constructed with an aluminum and ABS housing, the A107 4 x Lemo 2B SV module is built to perform reliably in industrial environments, withstanding a temperature range from -20 °C to +60 °C and humidity levels from 5 % to 95 % at 50 °C.

Communication and Compatibility

In addition to its versatile input channels and design, the Q.series X A107 4 x Lemo 2B SV module offers a wide range of communication and compatibility options to seamlessly integrate into various industrial systems. The Q.series X A107 4 x Lemo 2B SV module becomes a powerful and flexible tool for precise data acquisition and control in distributed installations.

  • Engineers can harness its direct EtherCAT capabilities, complemented by the use of a bus coupler for EtherCAT, for efficient and high-speed data exchange.
  • The module supports various interfaces such as CAN-FD, ModbusTCP, Profinet, OPC UA, and more when combined with the Q.station X, for compatibility with diverse control systems.

Long term Volcano Monitoring – A field study

Monitoring volcano activity is an important issue in the mitigation of natural hazards. Recently, most fatal issues occurred on volcanoes with low-energy and moderate activity, making them attractive touristic places (e.g., the 2014 Mount Ontake eruption in Japan). For these types of volcanoes, monitoring involves multiphysics measurements on dense networks. Distributed networks of sensors must be easily adapted to the volcano’s evolving state and the appearance of new active areas like fumaroles or high heat flux in the soil.
