8 Ch, 24-bit, 25.6 kS/s Universal Bridge Input Module

This document explains how to install, configure, and set up the NI PXIe-4339 SC Express

universal bridge module and TB-4339/4339B/4339C (TB-4339/B/C) terminal block. Driver

support for the NI PXIe-4339 was first available in NI-DAQmx 14.2. For the list of devices

supported by a specific release, refer to the NI-DAQmx Readme, available on the

version-specific download page or installation media.

Note The keying of these terminal blocks prevents them from connecting to other

modules that could be damaged by the voltage present on the terminal block.

However, you should only use these terminal blocks with their supported modules.

Electromagnetic Compatibility Guidelines

This product was tested and complies with the regulatory requirements and limits for

electromagnetic compatibility (EMC) stated in the product specifications. These requirements

and limits provide reasonable protection against harmful interference when the product is

operated in the intended operational electromagnetic environment.

This product is intended for use in industrial locations. However, harmful interference may

occur in some installations, when the product is connected to a peripheral device or test object,

or if the product is used in residential or commercial areas. To minimize interference with radio

and television reception and prevent unacceptable performance degradation, install and use this

product in strict accordance with the instructions in the product documentation.

Furthermore, any modifications to the product not expressly approved by National Instruments

could void your authority to operate it under your local regulatory rules.

Caution To ensure the specified EMC performance, operate this product only with

shielded cables and accessories. Cables connected to the PXIe-4339 using the

Installation

Install the Software

Note You must be an administrator to install NI software and devices on your

computer.

Ensure that the following software is installed before installing the SC Express hardware:

1. Your application software, such as LabVIEW, LabWindows™/CVI™or .NET.

2. NI-DAQmx—NI PXIe-4339 modules were first supported in NI-DAQmx 14.2.

Note For detailed NI software version support, refer to the NI-DAQmx Readme.

Back up any applications before upgrading software or modifying the application.

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 SC Express module while referring to Figures 1

and 2:

Note To maintain forced air cooling in the PXIe system, refer to the Maintain

Forced-Air Cooling Note to Users.

1. Plug in your chassis before installing the NI PXIe-4339. The power cord grounds the

chassis and protects it from electrical damage while you install the module.

2. Make sure the chassis is powered off.

Caution To protect yourself, the chassis, and the NI PXIe-4339 from electrical

hazards, leave the chassis powered off until you finish installing the NI PXIe-4339

module.

3. Touch a metal part on the chassis to discharge any accumulated static electricity.

4. Identify a supported PXI Express slot in the chassis. 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

5. Remove the filler panel, and touch any metal part of the chassis to discharge static

electricity.

6. 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.

7. 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.

8. 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.).

Figure 2. Installing SC Express Modules

Connect the Signals

Caution For EMC compliance, operate this product with shielded cables and

accessories.

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 Measurement & Automation

Explorer (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 signal wire by stripping the insulation no more than 7 mm (0.28 in.).

4. Run the shielded signal wires through the strain-relief opening.

5. Insert the stripped end of the shielded 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-4339 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.

Note Refer to the NI PXIe-4339 User Manual for wiring diagrams showing various

ways to connect sensors to the TB-4339/B/C.

6. Tighten the terminal screws to a torque of 0.2 to 0.25 N · m (1.77 to 2.21 lb · in.).

Caution Any wires connected to the ground must be sufficiently insulated from

high voltage.

7. Use the ground lugs to attach a shield wire to the ground.

Note Refer to the NI PXIe-4339 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 shielded 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.

Confirm SC Express Module Recognition

To confirm module recognition, complete the following steps:

Note Software support for the NI PXIe-4339 is provided by NI-DAQmx. The DAQ

Getting Started Guide, which you can download at ni.com/manuals, offers

step-by-step NI-DAQmx instructions for installing software and hardware,

configuring channels and tasks, and getting started developing an application. For

detailed NI software version support, refer to the NI-DAQmx Readme.

1. Launch MAX.

2. Expand Devices and Interfaces, and expand the chassis in which the module is located 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.
