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 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-4353.
Caution Refer to the Read Me First: Safety and Electromagnetic Compatibility document for
important safety and electromagnetic compatibility information. To obtain a copy of this document
online, visit ni.com/manuals, and search for the document title.

Installation
Step 1. Install the Software
Note You must be an administrator to install NI software and devices on your computer.
Before installing the NI SC Express hardware, make sure the following are installed in the order
indicated:
1. Your application software, such as LabVIEW, LabWindows™/CVI™or .NET.
2. NI-DAQmx 9.1 or later.
Note When installing NI application software, such as NI LabVIEW, refer to the NI-DAQmx
Readme on the software media 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 NI 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 modules.
5. Slide the module along the guides until it reaches the rear connector, then seat the module by
pushing the front panel until it is flush with the front panel of the chassis.
6. Secure the module to the chassis using the front-panel captive screws, shown in Figure 2. Tighten
the screws to 0.31 N·m (2.7 lb · in.).

Step 3. Connect the Signals
Caution To ensure the specified EMC performance, operate this product only with shielded cables
and accessories.
Note Refer to the Read Me First: Safety and Electromagnetic Compatibility document before
removing equipment covers or connecting or disconnecting any signal wires.
To connect signals to the terminal block, refer to Figures 3 and 4 while completing the following steps:
Note You can find the pinout names and locations in MAX at any time by right-clicking the device
name under Devices and Interfaces and selecting Device Pinouts.
1. Loosen the captive top cover screws and remove the top cover.
2. Loosen the strain-relief screws and remove the strain-relief bar.
3. Prepare the signal wire by stripping the insulation no more than 7 mm (0.28 in.).
4. Run the signal wires through the strain-relief opening.

5. Insert the stripped end of the signal wires fully into the appropriate terminal. Refer to the label next
to each screw terminal to determine the function of the terminal. The NI PXIe-4353 User Manual
provides more detailed wiring information. Make sure no exposed wire extends past the screw
terminal. Exposed wire increases the risk of a short circuit that can cause circuit failure.
Figure 4. TB-4353 Circuit Board Parts Locator Diagram
6. Tighten the terminal screws to a torque of 0.3 N·m (2.7 lb · in.).
Note In most applications, connection to the COM terminal is not necessary. However, its proper
connection will improve common-mode rejection performance when two or more channels are
connected to different common-mode voltages. In this case, connect COM to earth ground or a fixed
reference voltage, depending on your isolation requirements. All thermocouple channels with respect
to COM on the NI PXIe-4353 must remain within ±10 V. Refer to the NI PXIe-4353 User Manual
for more information about proper connection of the COM terminal.
Caution Any wires connected to the ground must be sufficiently insulated from high voltage.
7. Attach cable shields to the ground lugs to connect them to chassis ground.
Note Refer to the NI PXIe-4353 User Manual for details about shielding the signals.
8. Reinstall the strain-relief bar and tighten the strain-relief screws.
9. Use tie wraps to connect the signal wires to the tie-wrap holes for additional strain relief when
necessary.
10. Reinstall the top cover and tighten the captive top cover screws.

Step 5. 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.
