NI PXIe-4300 and TB-4300/B/C User Guide

Introduction

This document provides instructions for installing, configuring, and setting up the NI PXIe-4300 module with the TB-4300/B/C terminal blocks. It covers connecting signals, verifying system operation, and provides detailed specifications.

Current versions of NI documents are available at ni.com/manuals.

The TB-4300/B/C terminal blocks are designed for use with the NI PXIe-4300 module, supporting various measurement ranges:

• 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 terminal blocks are keyed to prevent connection to incompatible modules, protecting against damage from voltage differences.

[Caution] Ensure connected devices and circuits are properly insulated from human contact.

[Caution] When hazardous voltages (>30 Vrms/42.4 Vpk/60 VDC) are present, safety low-voltage connections are prohibited on other terminals.

[Caution] Do not supply hazardous voltages to the terminal block without it being connected to the NI PXIe-4300.

Installation

Install the Software

[Note] Administrator privileges are required to install NI software and devices.

Ensure the following software is installed before hardware installation:

• Application software (e.g., LabVIEW, LabWindows/CVI, .NET)
• NI-DAQmx (TB-4300/B supported from NI-DAQmx 9.1; TB-4300C from NI-DAQmx 15.1)

[Note] Refer to the NI-DAQmx Readme for detailed software version support. Back up applications before upgrading.

Unpack and Install the Module

Inspect the module upon unpacking. Contact National Instruments if the module is damaged. Do not install a damaged module.

[Caution] The module is static sensitive. Always ground yourself and equipment properly when handling or connecting.

Follow these steps to install the NI PXIe-4300:

1. Plug in the chassis before installing the module. The power cord grounds the chassis.
2. Ensure the chassis is powered off.
3. [Caution] To protect against electrical hazards, keep the chassis powered off until module installation is complete.
4. Touch a metal part of the chassis to discharge static electricity.
5. Identify a supported PXI Express slot (Peripheral, Hybrid Peripheral, or System Timing). Refer to chassis documentation for details.
6. Remove the filler panel and touch metal on the chassis to discharge static.
7. Place the module edges into the slot guides.
8. [Caution] Ensure module edges are within guides and components do not contact adjacent modules.
9. Slide the module to the rear connector and seat it by pushing the front panel until flush with the chassis.
10. Secure the module using the front-panel captive screws (refer to Figure 2). Tighten screws to 0.31 N·m (2.7 lb·in.).

Connect the Signals

[Note] Refer to "Read Me First: Safety and Electromagnetic Compatibility" before removing covers or connecting/disconnecting wires.

To connect signals to the terminal block (refer to Figures 3 and 4):

[Note] Pinout names and locations are available in Measurement & Automation Explorer (MAX) under Devices and Interfaces > Device Pinouts.

1. Loosen captive top cover screws and remove the top cover.
2. Loosen strain-relief screws and remove the strain-relief bar.
3. Strip signal wire insulation to no more than 7 mm (0.28 in.).
4. Run signal wires through the strain-relief opening.
5. Insert stripped wire ends into the appropriate terminals. Refer to terminal labels for function. The NI PXIe-4300 User Manual provides detailed wiring information. Ensure no exposed wire extends past the screw terminal to prevent short circuits.
6. [Note] For accurate measurements, connect the COM terminal to the AI source ground. For TB-4300C, connect AI- to COM.
7. Tighten terminal screws to 0.25 N·m (2.21 lb·in.).
8. [Caution] Wires connected to ground must be sufficiently insulated from high voltage.
9. Use ground lugs to attach shield wires to ground. Refer to the NI PXIe-4300 User Manual for shielding details.
10. Reinstall the strain-relief bar and tighten its screws.
11. Use tie wraps to secure signal wires to tie-wrap holes for additional strain relief.
12. Reinstall the top cover and tighten captive top cover screws.
