INSTALLATION GUIDE AND TERMINAL BLOCK

SPECIFICATIONS

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.

Installation

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 9.7 or later.

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.

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.

Note Refer to the NI PXIe-4322 User Manual for diagrams showing various ways

to connect a load to the TB-4322.

7. Tighten the terminal screws to a torque of 0.2 to 0.25 N ·m(1.77to2.21lb·in.).

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.

11. Reinstall the top cover and tighten the captive top cover screws.

Install the Terminal Block

Refer to Figure 5 to install the terminal block on the module while completing the following steps:

1. Move the TB-4322 into position in front of the NI PXIe-4322 and engage the alignment

feature with the guide on the associated module.

Figure 5. Installing the TB-4322 on the NI PXIe-4322 Module

2. Attach the TB-4322 to the NI PXIe-4322 module by pushing the terminal block straight

into the module. A spring mechanism will lock in the bottom of the terminal block.

3. Tighten the mounting screw at the top of the TB-4322 to attach it to the NI PXIe-4322

module.

Note For safety purposes and to prevent damage to equipment when high voltages

are present, all NI SC Express modules and terminal blocks are keyed to prevent

connection between incompatible terminal blocks, modules, and/or cables.

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, and expand 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.
