INSTALLATION GUIDE AND TERMINAL BLOCK SPECIFICATIONS NI PXIe-4357 and TB-4357 NI SC Express is a family of PXI Express modules with integrated data acquisition and signal conditioning. These devices offer increased speed, accuracy, and synchronization features that are well suited for high-density sensor measurement and signal-conditioning systems. Accessories required for signal connections to these modules include a front-mount terminal block with screw-terminal connectivity. This guide describes how to install and configure the NI PXIe-4357 module and TB-4357 terminal board, connect signals, and verify that the system is working properly. Current versions of NI documents are available at ni.com/manuals. The NI PXIe-4357 is a 20 channel RTD module. This module supports a range of accuracy modes that provide a range of measurement speeds. The NI PXIe-4357 supports 2-, 3- and 4-wire RTD measurements, as well as resistance measurements up to 400 Ω while providing an excitation current of 0.9 mA per channel. This terminal block is designed for use with the following module: NI PXIe-4357 Note Refer to the NI PXIe-4357 Specifications document for additional voltage and safety information. The keying of this terminal block prevents it from connecting to other modules that could be damaged by the voltage present on the terminal block. However, you should only use this terminal block with its supported modules. When hazardous voltages (>30 Vrms /42.4 Vpk/60 VDC) are present on any terminal, safety low-voltage (≤30 Vrms/42.4 Vpk /60 VDC) cannot be connected to any other terminal. Caution Do not supply hazardous voltages (>30 Vrms/42.4 Vpk/60 VDC) to the terminal block without the terminal block being connected to the NI PXIe-4357.
