NI PXIe-4322 and TB-4322
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-4322 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-4322 is an isolated, eight channel analog output module and is designed for use
with the TB-4322 terminal block.
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-4322.

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, and 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.

Connect the Signals
Caution To ensure the specified EMC performance, operate this product only with
shielded, twisted-pair cables and shielded accessories.
Caution To ensure the specified EMC performance, the length of all I/O cables
must be no longer than 30 m (100 ft).
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 shielded, twisted-pair cable by stripping the insulation and shield(s) to expose
sufficient signal wire to connect from just inside the strain relief bar to the desired screw
terminal. Ensure that the drain wire of the shielded cable is long enough to connect to one
of the two ground lugs inside the terminal block, which are shown in Figure 3.
4. Prepare the signal wire by stripping the insulation no more than 7 mm (0.28 in.).
5. Run the shielded, twisted-pair cable through the strain-relief opening.
Figure 3. TB-4322 Parts Locator Diagram
6. 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-4322 User Manual provides 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.

Caution Any wires connected to the ground must be sufficiently insulated from
high voltage.
8. Use the ground lugs to attach a shield wire to the ground. Attach the drain wire of the
shielded cable to a ground lug.
Note Refer to the NI PXIe-4322 User Manual for details about shielding the signals.
9. Reinstall the strain-relief bar and tighten the strain-relief screws.
10. Use tie wraps to connect the signal wires to the tie-wrap holes for additional strain relief
when necessary.
