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 Ensure that devices and circuits connected to the module are properly
insulated from human contact.
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-4300.

computer.
Ensure the following software is installed before installing the NI PXIe-4300 and TB-4300/B/C
hardware:
1. Your application software, such as LabVIEW, LabWindows™/CVI™, or .NET.
2. NI-DAQmx—The PXIe-4300 module and TB-4300/B terminal blocks were first supported
in NI-DAQmx 9.1. The TB-4300C terminal block was first supported in NI-DAQmx 15.1.
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 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.

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.

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.
Figure 4. TB-4300/B/C Circuit Board Parts Locator Diagram
6. Tighten the terminal screws to a torque of 0.25 N · m (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-4300 User Manual for details about shielding the
signals.

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.
