This document describes how to install, configure, and set up the NI PXIe-4300 with the

TB-4300/4300B/4300C (TB-4300/B/C) terminal block, connect signals, and verify that the

system is working properly. Current versions of NI documents are available at ni.com/

manuals.

The TB-4300/B/C terminal blocks are designed for use with the following module as specified:

NI PXIe-4300 ................................................... 10 V maximum voltage measurement range,

AI+ to AI-

TB-4300.................................................... 10 V maximum voltage measurement range,

AI+ to AI-

TB-4300B ................................................. 300 V maximum voltage measurement range,

AI+ to AI-

TB-4300C ................................................. 20 mA maximum current measurement range,

AI+ to AI-

Note The keying of these terminal blocks prevent 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.

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-4300.

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 PXIe-4300 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-4300. 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-4300 from electrical

hazards, leave the chassis powered off until you finish installing the NI PXIe-4300

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. NI PXIe-4300 modules 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 NI PXIe-4300 Modules

Connect the Signals

Note Refer to the Read Me First: Safety and Electromagnetic Compatibility 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-4300 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 For accurate measurements, the COM terminal for the channel being used

must be connected to the ground of the AI source being measured. For the TB-4300C,

connect AI- to COM for the channel being used.

6. Tighten the terminal screws to a torque of 0.25 N·m(2.21lb·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-4300 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.

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-4300/B/C into position in front of the NI PXIe-4300 and engage the

alignment feature with the guide on the associated module.

Figure 5. Installing the TB-4300/B/C on the NI PXIe-4300 Module

2. Attach the TB-4300/B/C to the NI PXIe-4300 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-4300/B/C to attach it to the NI PXIe-4300

module.

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

are present, all NI PXIe-4300 modules and terminal blocks are keyed to prevent

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

4. Power on the chassis.

Confirm NI PXIe-4300 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 PXIe-4300 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.
