National Instruments 783531-01 PXI Strain/Bridge Input Module
The National Instruments 783531-01 is also known as the PXIe-4339 unit. It is an 8-channel PXI strain/bridge input module designed for precise and versatile data acquisition in test cell installations. This module is equipped with 24-bit Delta-Sigma ADCs that enable simultaneous sampling across all channels that ensure accurate and reliable measurements. It supports multiple input ranges in both ratiometric and voltage modes along with voltage ranges of ±100 mV, ±200 mV, ±500 mV, and ±10 V.
The NI 783531-01 offers comprehensive bridge completion options that include half-bridge and quarter-bridge completion along with shunt calibration functionality to ensure measurement accuracy. The module’s programmable excitation feature allows for constant differential voltage across a range of values, from 0.625 V to 10 V that makes it adaptable to different measurement needs. This module is ideal for applications requiring high-fidelity signal processing due to per-channel wide bandwidth analog outputs and digital filtering.
The 783531-01 unit utilizes direct memory access (DMA) and programmed I/O for efficient data transfers. It supports a sampling rate range from 1 S/s to 25.6 kS/s along with a FIFO buffer size of 1,023 samples. The module’s hardware-timed single-point sample mode allows for precise acquisition rates. This input module also features TEDS (Transducer Electronic Data Sheet) support that enhances the ease of sensor integration and configuration. It is equipped with both analog and digital triggering options. The 783531-01's robust design includes a 100 MHz internal frequency timebase with high accuracy.
This model is designed for demanding environments and can operate at the maximum altitude of 2000 MSL under the rated temperature range of 0 °C to 55 °C. It complies with stringent safety and electromagnetic compatibility standards that include IEC 61010-1 and EN 61326-2-1. It is built to withstand significant shock and vibration that makes it a reliable choice for industrial and laboratory settings. With a compact 3U PXIe form factor, this module integrates seamlessly into PXI Express systems. This NI 783531-01 unit weighs only 186 g (6.6 oz.) and measures 16 cm × 10 cm (6.3 in. × 3.9 in.) in size.
