The National Instruments PXI-6511 Digital I/O Module (Part Number: 778967-01) is a robust solution designed for industrial applications, offering 64 channels of bank-isolated, sink/source digital I/O with a voltage range of -30 VDC to +30 VDC. Operating at 24 V logic levels, this module features eight fully isolated banks, enhancing its capability to handle diverse industrial tasks safely. In the event of software or hardware faults, the PXI-6511 employs integrated digital I/O watchdogs to activate a user-defined safe output state, facilitating prompt fault detection and recovery. With programmable input filters, the module effectively eliminates signal spikes and provides adequate denouncing, making it compatible with digital relays and switches.

Accessing digital input lines is streamlined through a high-density 100-pin keyed female SCSI connector, with input photocouplers designed to respond to voltage differentials and increases. Users can customize power-up states through the Measurement & Automation Explorer (MAX) tool, ensuring controlled device initialization. This model offers a comprehensive digital filtering option to reduce glitches and minimize input changes, particularly when employed with the change detection feature.

The PXI-6511 operates with the NIDAQmx driver software, compatible with various software packages and application development environments such as LabVIEW and LabWindows/CVI. It also allows customization of digital filter timings to suit user requirements. The module measures 8.38 x 5.12 inches and weighs 4.8 ounces, featuring a temperature range of 0 to 55 °C for operation and -20 to 70 °C for storage, along with humidity specifications of 10 to 90% operating and 5 to 95% non-operating. The PXI-6511 is backed by a three-year warranty. For pricing and detailed documentation, including the user and maintenance manual, please contact a sales representative.
