The National Instruments PXI-6514 is a robust industrial-grade Digital I/O Module designed for PXI systems, featuring 64 channels with an isolated ±30 VDC input/output configuration. Comprising 32 source/sink input lines and 32 source output lines, the PXI-6514 is ideal for general-purpose data acquisition, automated manufacturing testing, and industrial control applications. Its isolated banks ensure safe operation with industrial process actuators, allowing users to software-configure initial output states to prevent unintended behaviors.

The module supports DC signal detection within a range of 11 to 30 V, where it registers a logic high at input voltages of 11 V or greater, and a logic low with 4 V or less. The PXI-6514 enhances operational reliability with programmable power-up states, making it suitable for interfacing with various devices such as relays, pumps, motors, and valves. Key features include digital filtering for noise reduction, NI's digital I/O watchdog technology for fault protection, and change detection capabilities that trigger software applications to execute digital read operations upon state changes.

Connectivity is facilitated via a 100-pin high-density SCSI connector, compatible with standard ribbon cables or shielded cables, such as the R1005050 ribbon cable paired with CB-50 or CB-50LP Connector Blocks for unshielded connections, or the SH100-100-F Shielded Digital I/O Cable with the CB-37FH DIN-rail-mountable Connector Block for shielded setups. The PXI-6514 measures 6.3 x 3.9 inches and weighs 6.1 ounces, making it a compact yet powerful addition to any industrial control system. For software integration, it utilizes the NIDAQmx driver, compatible with popular application development environments like LabVIEW and LabWindows/CVI. The module is backed by a 2-3 year warranty, and user manuals for operation and maintenance are available for download. For pricing information, please contact a sales representative.
