Precise data acquisition with new multiplexer PCIe DAQ cards

March 18, 2025 - PRLog -- PCIe-DAQ cards (Peripheral Component Interconnect Express - Data Acquisition Cards) are a key technology in measurement applications and form the high-performance interface for digital signal processing and data acquisition.

One example from the new series of high-resolution PCIe DAQ cards is the PCIe-9103 for 32 channels. The PCIe-9103 offers the high input resolution of up to 16 bits and 500 kS/s sampling rate. It supports a wide range of ±10 V to ±0.3125 V for the input voltage, which enables flexible adaptation to different measurement environments. The card is equipped with two encoder channels and supports CW/CCW and x1/x2/x4 AB-phase encoder protocols for easy integration into motion control applications.

The direct connection to the PCIe bus enables the high data transfer rate to be achieved with low latency, which is of crucial importance in numerous application areas such as research, industrial automation, test systems and production control. A further advantage is Direct Memory Access (DMA), which makes it possible to transfer data directly between the card and the main memory, thus significantly reducing CPU utilisation. This leads to improved system performance and shorter response times. The card also has the option of automatic calibration, which enables quick and easy set-up. The ID switch on the board ensures clear and easy identification when several cards are used in the same system. Especially during commissioning and maintenance, this visual control option is an advantage compared to identification that can only be read by software.

All DAQ cards in the PCIe-9100 series are CE and RoHS compliant and can be used in temperatures ranging from 0 to 60 °C. The cards offer the ideal solution for companies and research institutions that require high performance, versatility and precision. Their flexible configuration and comprehensive functionality make them efficient tools in intelligent measurement, control and automation systems. The DAQPilot software provided by the manufacturer offers users efficient mass device management and supports the remote monitoring of system components.
