NI PXIe-4353 and TC-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. The
TC-4353 rack-mount terminal block accessories provides thermocouple plug-in terminal
connectivity.
This guide describes how to install and configure the NI PXIe-4353 module and TC-4353
terminal block, thermocouple connector 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 TC-4353 terminal block has eight thermistors that provide CJC for
thermocouples.
The TC-4353 terminal block is designed for use with the following module as specified:
NI PXIe-4353 ................................................... ±80 mV maximum voltage measurement range
Caution Do not supply hazardous voltages (>30 Vrms/42.4 Vpk/60 VDC) to the
TC-4353 terminal block.
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.

Cold-Junction Compensation
Cold-junction compensation is the process of measuring the temperature of the junction for the
thermocouple and applying a representative compensating voltage to the voltage measured by
the thermocouple channel. The accuracy of the cold-junction temperature measurement is a key
part of the accuracy of the overall thermocouple temperature measurement. The TC-4353 is
carefully designed to ensure high-accuracy cold-junction temperature measurements, under a
variety of conditions; however, care must be taken to ensure the best possible accuracy. Refer to
the Minimizing Thermal Gradients section for guidelines to minimize thermal gradients that
could impact the CJC accuracy. Refer to the Specifications section for the CJC accuracy
specifications.
The TC-4353 contains eight thermistors that are used to measure the temperature of the adjacent
thermocouple junctions for the CJC that is performed when computing the thermocouple
temperature measurement. These eight thermistors are measured using the CJC channels on the
NI PXIe-4353 module. Each thermistor measures the CJC temperature for a subset of associated
thermocouple channels. Figure 6 shows the CJC grouping locations. The dashed lines indicate
the channel to CJC associations found in Table 2. NI-DAQmx automatically associates the
correct thermistor with the thermocouple measurements when you use the Thermocouple
Channel-Type and select built-in for the CJC source.

Minimizing Thermal Gradients
Thermal gradients can be caused by changes in the ambient air temperature near the terminal
block, heat sources from other devices near the terminal block, or by the thermocouple wire if it
conducts heat to or away from the terminal junctions. For optimal CJC accuracy performance,
ensure that changes in ambient temperature and temperature gradients near the terminal block
are kept to a minimum. Follow these guidelines to minimize thermal gradients that could impact
the CJC accuracy:
• Use the smallest gauge thermocouple wire suitable for the application. Smaller wire
transfers less heat to or from the terminal junction.
• Run thermocouple wiring together near the terminal block to keep the wires at the same
temperature.
• Avoid running thermocouple wires near hot or cold objects.
• If you connect any extension wires to thermocouple wires, use wires made of the same
conductive material as the thermocouple wires.
• Minimize adjacent heat sources and air flow across the terminal block.
• Keep the ambient temperature as stable as possible.
• Keep the terminal block, module, and chassis in a stable and consistent orientation.
• Install the PXIe filler panels in any unused slots.
• When stacking the system, avoid stacking the terminal block above a heat source as heat
rises and can introduce error.
• Allow the thermal gradients to settle after a change in system power or in ambient
temperature. A change in system power can happen when the system powers on. Refer to
the warm-up time in the NI PXIe-4353 Specifications for more information.
• Replace, clean, or remove the fan filters in the PXIe chassis regularly to ensure proper
system cooling.
Calibrate the Module and Terminal Block
You can download available external calibration documents from ni.com/calibration by
clicking Manual Calibration Procedures. For external calibration of products not listed there,
Basic Calibration Service or Detailed Calibration Service is recommended. You can get
information about both of these calibration services at ni.com/calibration.
NI recommends performing an external calibration once a year.
