National Instruments PXIe-6345 PXI Multifunction I/O Module
The PXIe-6345 (Part Number: 783631-01, 156605B-04L, 256605B-04L) is a PXI Multifunction I/O Module from National Instruments. This X Series module offers either 40 differential or 80 single-ended channels, incorporating an analog to digital converter (ADC) with a resolution of 16 bits. The maximum sample rate for the module is 500 kS/s either a single channel or multiple channels. Designed for high quality connectivity, the PXIe-6345 features 24 digital I/O channels and a 68-pin VHDCI I/O Connector.
The NI PXIe-6345 module offers a timing resolution of 10 Nanoseconds, with a timing accuracy of 50 parts per million. The input of the device implements DC coupling, and it has four counters with 32 bits of resolution. The counters enable the user to carry out various operations for different testing requirements, including event counting, encoding, pulse width modulation, and many more. The Multifunction I/O Module also offers data logging capabilities, helping the user control and automate testing procedures.
The National Instruments PXIe-6345 offers an incredibly high throughput of data, allowing the module to deliver an excellent and reliable performance even at the industrial level. Additionally, the instrument boasts built-in NI-STC3 technology, which features timing and synchronization capabilities. This module enables analog and digital timing engines, offering analog triggers that also have 16 bits of resolution. These analog triggers can operate in different modes including analog edge triggering and window triggering- with the additional option of analog edge triggering with hysteresis.
Physically, the PXIe-6345 weighs around 198 g (7.0 oz) and measures the same dimensions as a standard 3U PXI. In terms of power, the device draws 1.6 W of power for a voltage of +3.3 V, and 19.8 W for a voltage of +12 V. Connector 0, a +5 V terminal of the module, has a maximum current limit of 1 A. While being used, the operating temperature range of the device spans from 0 to 55 ºC. When non-operational, the device has a storage temperature range of -40 to 70 ºC. The noncondensing relative humidity for both operating and storage conditions is 10 to 90% and 5 to 95%, respectively.
