The National Instruments PXI-6529 (Part Number: 779949-01) is a robust 48-channel digital I/O module designed for the PXI platform, featuring isolated channel-to-channel architecture and configurable sink/source inputs. This module offers an extensive digital input voltage range of -60 V to 60 V, with digital I/O logic levels reaching up to 60 V, making it ideal for applications across industrial factory automation, automotive design, machine control, and biomedical fields. Key functionalities include change detection, digital filtering, and real-time system integration, allowing for efficient monitoring and signal processing. The module is equipped with a PXI start trigger for coordinated input operations and offers eight output lines. Users can configure inputs and outputs through Port 0 and Port 3, respectively, enabling flexible signal routing.

When the change detection feature is active, the module can signal detected changes on any of the input lines. It is capable of generating a 200 ns pulse to any RTSI line upon detection, enhancing responsiveness in dynamic environments. Connectivity is facilitated via a 100-pin high-density SCSI connector, granting access to all 48 digital inputs. The logical operation of the PXI-6529 is defined such that a logic low occurs when no voltage or current is present, while a logic high indicates a closed switch position and active current flow. The module operates with a current requirement of 250 mA at +5 VDC (±5%) and 400 mA at +3.3 VDC (±5%). It is compatible with the NI-DAQmx driver software, supporting various application development environments such as LabVIEW and LabWindows/CVI, and can be verified using the Measurement & Automation Explorer (MAX). The PXI-6529 has a compact profile at 6.3 inches by 3.9 inches and weighs 4.6 oz, with operating and storage temperature ranges of 0 to 55 °C and -20 to 70 °C, respectively. Users benefit from a comprehensive three-year warranty, with manuals available for download to assist in setup and maintenance. For pricing information, please contact a sales representative.
