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

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.
