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.

Note When installing NI application software, such as NI LabVIEW, refer to the
NI-DAQmx Readme on the software disc for supported software versions. Back up
any applications before upgrading software or modifying the application.
Tip Using an NI-DAQmx simulated device, you can test NI-DAQmx applications
without installing hardware. Refer to the Create a Simulated Device section for
instructions for creating NI-DAQmx simulated devices.
Step 2. Unpack and Install the Module
Remove the packaging and inspect the module. Contact NI if the module is damaged. Do not
install a damaged module.
Caution The module is static sensitive. Always properly ground yourself and the
equipment when handling or connecting to the module.
Complete the following steps to install the NI SC Express module while referring to Figures 1
and 2:
1. Power off the PXI Express chassis. Refer to the chassis manual for chassis installation and
configuration instructions.
Caution Refer to the Read Me First: Safety and Electromagnetic Compatibility,
included with your module, before connecting or disconnecting signal wires.
2. Identify a supported PXI Express slot in the chassis. NI SC Express devices can be placed
only in PXI Express Peripheral slots, PXI Express Hybrid Peripheral slots, and
PXI Express System Timing slots. Refer to the chassis documentation for details.
Figure 1. Symbols for PXI Express/PXI Express Hybrid/PXI Slots
3. Remove the filler panel and touch any metal part of the chassis to discharge static
electricity.
4. Place the module edges into the module guides at the top and bottom of the slot.
Caution When installing the module, make sure both edges are positioned inside
the guides and that the module components do not come into contact with adjacent

To install the cables, complete the following steps while referring to Figures 3 and 4.
Note For safety purposes and to prevent damage to equipment when high voltages
are present, the SH96-96-1 cable is keyed to prevent connection between
incompatible terminal blocks, modules, and/or cables.
1. Connect the shield drain wire of the shielded thermocouple wire to the chassis ground
screw, shown daisy chained in Figure 3. Make the shield drain wire as short as practical for
your application.
2. Connect the COM wires to the COM terminals.
3. Connect the thermocouple miniconnectors to the appropriate thermocouple miniconnector
receptacles.
4. Screw the two standoffs into the NI PXIe-4353 module. Tighten the standoffs to 0.90 N ·m
(8.0 lb · in.).
5. Connect the male end of the SH96-96-1 cable to the TC-4353 and tighten the two jack
screws to 0.90 N ·m(8.0lb·in.).
6. Connect the female end of the SH96-96-1 cable to the NI PXIe-4353 and tighten the
two jack screws to 0.90 N ·m(8.0lb·in.).

Step 4. Confirm NI SC Express Module Recognition
To confirm module recognition, complete the following steps:
Note Make sure you are using the most recent version of NI-DAQmx. If you are
using an older version of the driver software, the NI SC Express terminal block may
work only in basic functionality mode. Unsupported terminal blocks appear in
Measurement & Automation Explorer (MAX) with an X next to them.
1. Launch MAX.
2. Expand Devices and Interfaces»NI-DAQmx Devices to confirm that MAX detects the
module and terminal block. The terminal block should appear beneath its associated
module. If your module or terminal block is not listed, press <F5> to refresh MAX. If the
module is still not recognized, go to ni.com/support/daqmx.
Tip Using an NI-DAQmx simulated device, you can test NI-DAQmx applications
without installing hardware. Refer to the Create a Simulated Device section for
instructions for creating NI-DAQmx simulated devices.
3. Right-click the module name and select Self-Test. When the self-test completes, a
verification message appears. If an error occurs, refer to ni.com/support/daqmx.
For information about sensors, go to ni.com/sensors.

2. Right-click the device, and select Test Panels.
3. Click Start to test device functions, or Help for operating instructions.
To troubleshoot errors, refer to the NI-DAQmx Help, or go to ni.com/support.
Step 6. Take an NI-DAQmx Measurement
NI-DAQmx Channels and Tasks
Refer to the NI-DAQmx Help for complete information about channels and tasks.
Use the DAQ Assistant to configure virtual channels and tasks in MAX or in your application.
Configure a Task Using the DAQ Assistant from MAX
Complete the following steps to create a task using the DAQ Assistant in MAX:
1. In MAX, right-click Data Neighborhood and select Create New to open the
DAQ Assistant.
2. Select NI-DAQmx Task and click Next.
3. Select Acquire Signals.
Note The NI PXIe-4353 cannot generate signals.
4. Select Analog Input and the measurement type, such as Temperature»Thermocouple
or Voltage.
5. Select the physical channel(s) to use and click Next.
6. Name the task and click Finish.
7. Configure the individual channel settings. Each physical channel you assign to a task
receives a virtual channel name. To modify the input range or other settings, select the
channel. Click Details for physical channel information. Configure the timing and
triggering for your task. Click Run.
