Description
The National Instruments PCI-4351 is a multifunction DAQ device with a part number of 777789-01, designed to measure temperature with RTDs, thermocouples, and thermistors, as well as perform chromatography, resistance, and analog signal measurements.
This device supports a voltage range of up to ±15 V and offers 16 differential or 32 single-ended analog input channels with a high-resolution 24-bit ADC converter. It provides six selectable reading rates to accommodate different measurement needs.
Equipped with 8 digital I/O lines that are TTL compatible, the PCI-4351 ensures compatibility with various digital devices. The precision of temperature measurements is highly accurate, with ±0.42 °C for J-type thermocouples, ±0.12 °C for RTDs, and ±0.03 °C for thermistors.
Voltage measurement is precise with a 5 1/2 digit resolution, and connectivity is provided through a 68-pin male I/O connector. The device includes a feature for current source for thermistor excitation and RTD, enhancing the accuracy of temperature readings. Additionally, it offers software-selectable ground which allows for the measurement of both ground-referenced and floating signals.
