Overview
The NI PXIe-4300 isolated analog input module provides data acquisition with integrated signal conditioning for high-voltage measurements. It features eight channels with 300
Vrms channel-to-channel isolation and simultaneous sampling up to 250 kS/s per channel. For accurate measurements, the NI PXIe-4300 offers programmable lowpass filters (10
kHz, 100 kHz, bypass) per channel. You can choose the NI TB-4300 terminal block for 1, 2, 5, and 10 V signal inputs or the TB-4300B for 30, 60, 150, and 300 V signal inputs.
The TB-4300 and TB-4300B are front-mounting terminal blocks with screw terminal connectivity.

Application and Technology
Integrated Signal Conditioning
By combining signal conditioning and analog-to-digital converters (ADCs) on the same device, the NI PXIe-4300 isolated analog input module delivers a smaller footprint and
higher measurement performance. Integrated signal conditioning also provides simplified cable management and calibration due to fewer components, which drastically reduces
the installation and maintenance cost of a high-channel-count measurement system.
Safety and Accuracy with Channel-to-Channel Isolation
Isolation is needed for safe operation around high voltages. The NI PXIe-4300 has 300 V
rms
of continuous channel-to-channel isolation for measurements with differing potentials
as well as 3,300 V
rms
transient withstand for protection from sudden voltage spikes. In addition to offering increased safety, channel-to-channel isolated systems are more
accurate and easier to set up due to the elimination of ground loops.
PXI Express Dedicated Data Throughput
The SC Express modules are built on the x1 PXI Express bus with dedicated bandwidth per device up to 250 MB/s. Because of the added bandwidth provided by PXI Express,
SC Express modules offer simultaneous sampling options using the same channel counts and connectivity as multiplexed devices. Unlike multiplexed devices that reduce
sampling rates, you can use simultaneous sampling devices to maintain sampling rates as you expand the number of channels.
PXI Platform Advanced Timing and Synchronization
PXI Express provides advanced timing and synchronization features, including a 100 MHz differential system clock, differential signaling, and differential star triggers. By using
differential clocking and synchronization, PXI Express systems benefit from increased noise immunity for instrumentation clocks and the ability to transmit at higher-frequency
rates. The SC Express family leverages PXI Express to deliver tight synchronization between modules in one chassis or multiple chassis.
Wide Variety of I/O on the PXI Platform
When combined with more than 1500 I/O types in the PXI platform, this module offers the flexibility needed to develop a measurement system that meets your application needs.
PXI modules are compatible with the CompactPCI and CompactPCI Express industrial computer standards and offer additional features such as environmental specifications,
standardized software, and built-in timing and synchronization.
Connectivity
1/9
www.ni.com
The NI PXIe-4300 is designed to be used with the NI TB-4300 and TB-4300B front-mounting terminal blocks. You can choose the TB-4300 for 1, 2, 5, and 10 V signal inputs or
the TB-4300B for 30, 60, 150, and 300 V signal inputs. The terminal blocks are hot-swappable and automatically recognized in software. This makes troubleshooting easier
because you can connect and remove terminal blocks without powering down the PXI measurement system. Each terminal block also includes alignment fins that guide the
connector onto the PXI Express module without bent pins.

Support and Services
System Assurance Programs
NI system assurance programs are designed to make it even easier for you to own an NI system. These programs include configuration and deployment services for your NI PXI,
CompactRIO, or Compact FieldPoint system. The NI Basic System Assurance Program provides a simple integration test and ensures that your system is delivered completely
assembled in one box. When you configure your system with the NI Standard System Assurance Program, you can select from available NI system driver sets and application
development environments to create customized, reorderable software configurations. Your system arrives fully assembled and tested in one box with your software preinstalled.
When you order your system with the standard program, you also receive system-specific documentation including a bill of materials, an integration test report, a recommended
maintenance plan, and frequently asked question documents. Finally, the standard program reduces the total cost of owning an NI system by providing three years of warranty
coverage and calibration service. Use the online product advisors at ni.com/advisor to find a system assurance program to meet your needs.
Calibration
NI measurement hardware is calibrated to ensure measurement accuracy and verify that the device meets its published specifications. To ensure the ongoing accuracy of your
measurement hardware, NI offers basic or detailed recalibration service that provides ongoing ISO 9001 audit compliance and confidence in your measurements. To learn more
about NI calibration services or to locate a qualified service center near you, contact your local sales office or visit ni.com/calibration.
