The National Instruments PXI-6515 is a 64-channel, ±30 VDC PXI Digital I/O Module designed for industrial automation applications. This module includes eight isolated channels, allowing users to configure each input bank for either sink or source functionality. It incorporates programmable power-up states, ensuring safe operation when interfaced with industrial actuators. Additionally, the digital I/O watchdogs facilitate automatic switching to a secure output state, thereby enhancing reliability in fault scenarios. The PXI-6515 comprises 32 source/sink inputs and 32 sink outputs, and it is equipped with a 100-pin keyed female SCSI D-type connector for compatibility with shielded cables or 100-pin ribbon cables. Each port provides up to 125 mA across all channels, with a maximum of 500 mA for a single channel. The module also supports 24 V logic thresholds. Noteworthy features include programmable input filters designed to eliminate noise and transient spikes, as well as high-current drive capabilities. Easy integration is supported through the NI-DAQmx measurement services software, compatible with multiple programming environments such as LabVIEW, Visual C#, Visual Studio.NET, Measurement Studio, LabWindows/CVI, and ANSI C/C++. The PXI-6515 operates with Microsoft Windows XP and Windows Vista (x64/x86) and offers robust fault protection against various system failures, including PCI bus, application, driver, and complete operating system crashes. This module is backed by a three-year warranty, and a user manual is available for download. For pricing information, please contact a sales representative.
