The National Instruments PXI-6514 is a 64-channel isolated digital I/O module with a ±30 VDC voltage range, entirely software configurable without jumpers, featuring programmable power-up states, digital filtering, NI digital I/O watchdog technology
The National Instruments PXI-6514 PXI Digital I/O Module, with part number 778965-01, is a versatile and robust data acquisition device offering a 64-channel configuration that includes 32 digital inputs (DI) and 32 digital outputs (DO). This module operates within a voltage range of ±30 VDC and is isolated to protect against electrical interference.
Input logic levels are clearly defined with a high logic level ranging from 11 to 30 V and a low logic level being 4 V or less, ensuring reliable signal processing. The PXI-6514 is entirely software configurable, eliminating the need for manual jumper settings and streamlining setup and changes.
Programmable power-up states can be set for safety and control in automated environments. With built-in digital filtering, the module is adept at reducing signal noise and avoiding false triggering. The inclusion of NI’s digital I/O watchdog technology provides a safeguard against system malfunctions, such as crashes or unresponsive applications.
Change detection capability allows for efficient monitoring, as the module can trigger a notification or action upon detecting a change in state. Compatibility with NIDAQmx driver software and integration with development platforms like LabVIEW and LabWindows/CVI make this module a flexible choice for engineers and developers.
Connection to the module is made simple with a 100-pin high-density SCSI connector, and various cable and connector block options, including the R1005050 ribbon cable and CB-50 or CB-50LP Connector Blocks for unshielded connectivity, or the SH100-100-F Shielded Digital I/O Cable and the CB-37FH DIN-rail-mountable Connector Block for shielded setups. Despite its extensive capabilities, the PXI-6514 maintains a compact form factor with a weight of just 6.1 oz.
