Description
The Part Number 781348-01 refers to a high-performance SC Express module, specifically the PXIe-4353. This module is designed for advanced thermal measurement applications, featuring 32 thermocouple analog input channels in a differential configuration. It offers analog input isolation of 300 V, ensuring safety and reliability in high-voltage environments.
In addition to its main input channels, the PXIe-4353 includes 2 auto zero and 8 cold junction compensation channels, enhancing measurement accuracy and stability. The module comes with a built-in TB-4353 isothermal terminal block, designed to minimize thermal errors and simplify setup.
Utilizing a Delta-Sigma ADC, the module operates in a scan sampling mode, with a maximum sample rate of 90 samples per second (S/s). It can measure voltages in the range of ±80 mV, with a differential input impedance of 20 mega-ohms. The device boasts impressive accuracy, with a DC linearity that is typically 20 ppm and at most 60 ppm.
When the OTD (Open Thermocouple Detection) mode is enabled, the input current is 17 Nano-amperes, and when disabled, it is 400 Pico-amperes. The module is compatible with a range of software, including NI-DAQmx, LabVIEW, LabWindows/CVI, and Measurement Studio, ensuring ease of integration into existing systems.
The PXIe-4353 supports a channel to channel voltage range of ± 10 volts (common mode), and its voltage range relative to Earth ground is ± 300 volts. It features a Common Mode Rejection Ratio (CMRR) of 100 dB and provides overvoltage
