Description
The 781348-01 is a part of the SC Express category and is identified by the model PXIe-4353. This product is a System Element, IES, CCA, TB-4353, ISO Thermal Terminal Block specifically designed for use with the PXIe-4353. It is equipped with 32 thermocouple analog input channels which are differential in nature. In addition to these primary channels, it also features 2 auto zero and 8 cold junction compensation channels for enhanced measurement accuracy.
The analog input isolation provided by this device is rated at 300 V, ensuring a high level of protection against voltage spikes. The sampling mode is scanned, utilizing a Delta-Sigma ADC Type for high-fidelity data conversion. With a maximum sample rate of 90 S/s, it offers a balance between speed and accuracy for a variety of thermal measurement applications.
The voltage measurement range is quite flexible at ±80 mV, with a differential input impedance of 20 mega-ohms. The device showcases excellent linearity with a typical DC linearity of 20 ppm and a maximum DC linearity of 60 ppm. The Open Thermal Couple Detection (OTD) Mode is software selectable, which allows for precise monitoring and troubleshooting of the thermal couple’s integrity. When OTD is enabled, the input current is as low as 17 Nano-amperes, and when disabled, it drops even further to 400 Pico-amperes.
This system is compatible with a range of software including NI-DAQmx, LabVIEW, LabWindows/CVI, and Measurement Studio, making it a versatile choice for various data acquisition and analysis applications. The device supports a channel to channel voltage range of ±10 volts (Common Mode) and a voltage range (
