TERMINAL BLOCK INSTALLATION GUIDE AND SPECIFICATIONS
NI PXIe-4353 and TB-4353
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 SC Express PXIe-4353 module and terminal
block, connect signals, and verify that the system is working properly. Current versions of NI documents
are available at
ni.com/manuals
.
The NI PXIe-4353 is a high-accuracy thermocouple input module that supports up to 32 thermocouple
inputs and has 8 cold-junction compensation (CJC) channels for improved CJC accuracy. The TB-4353
terminal block has eight thermistors that provide CJC for thermocouples.
The TB-4353 terminal block is designed for use with the following module as specified:
NI PXIe-4353.........................................................±80 mV maximum voltage measurement range
Note
Refer to the
NI PXIe-4353 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.
Caution
When hazardous voltages (>30 V
rms
/ 42.4 V
pk
/60 VDC) are present on any terminal, safety
low-voltage (
30 V
rms
/42.4 V
pk
/60 VDC) cannot be connected to any other terminal.
Caution
Do not supply hazardous voltages (>30 V
rms
/42.4 V
pk
/60 VDC) to the terminal block
without the terminal block being connected to the NI PXIe-4353.
Caution
