Product Introduction
Земля NI PXIe-6345 is a high-channel-count X Series multifunction data acquisition module designed for automated testing, industrial monitoring, laboratory measurement, and large-scale sensor acquisition systems. It combines analog input, analog output, digital I/O, counter/timer functionality, analog triggering, and PXI Express synchronization resources in a single modular instrument.
With up to 80 single-ended or 40 differential analog input channels, 16-bit resolution, and a maximum aggregate sampling rate of 500 kS/s, the PXIe-6345 is well suited for systems that need to measure many voltage signals without installing multiple lower-density DAQ modules.
Product Overview
Земля PXIe-6345 belongs to the NI X Series multifunction I/O family and is optimized for high-channel-count, multiplexed analog acquisition. It supports seven programmable input ranges from ±0.1 V to ±10 V, helping engineers measure both low-level and general-purpose voltage signals with one module.
In addition to its analog input subsystem, the PXIe-6345 provides two 16-bit analog outputs, 24 programmable 5 V TTL digital I/O lines, four 32-bit counter/timers, analog and digital triggering, and advanced NI-STC3 timing resources.
The module uses a PXI Express interface for high-speed communication with an embedded or remote system controller. It is supported by NI-DAQmx and can be integrated into measurement applications developed with LabVIEW, TestStand, C/C++, .NET, Python, and other supported programming environments.
