The National Instruments 778317-01, also known as the PCI-4452 Dynamic Signal Acquisition Device, is engineered for high-performance signal acquisition in a wide variety of applications. This device features four simultaneously sampled, true differential analog input channels, providing a resolution of 16 bits and leveraging a Delta-sigma ADC with 128-times oversampling for enhanced accuracy. The device supports sample rates from 5 kS/s to 204.8 kS/s in increments of 190.735 µS/s and includes a FIFO buffer with a size of 512 samples for efficient data handling. Data transfer is versatile, allowing for DMA, programmed I/O, or interrupt-driven operations. Additionally, the PCI-4452 offers eight digital I/O channels, compliant with TTL/CMOS standards, featuring input voltage ranges from 0.0 V to 0.8 V for low states and 2.0 V to 5.0 V for high states. Outputs are defined as low for voltages up to 0.4 V and high for voltages starting at 4.35 V. Power-on defaults for these channels are configured to high-impedance input. The device also includes two 24-bit up/down counter/timers and one 4-bit frequency scaler, all functioning under a base clock of 20 MHz for the counters/timers and 10 MHz for the scaler, with data transfer modes mirroring those of the I/O channels. Physically, the module measures 4.19 x 12.28 x 0.73 inches (excluding connectors) and is equipped with a 68-pin VHDCI female connector for analog I/O and a 50-pin VHDCI female connector for digital I/O. The PCI-4452 operates effectively in environments ranging from 0 °C to +40 °C at a relative humidity of 10% to 95%, with storage capabilities between −25 °C and +85 °C. The device requires calibration every year to maintain optimal performance.
