National Instruments 779949-01 DIgital I/O Module
National Instruments part number 779949-01 is an identifying part number for the PXI-6529, an Isolated PXI Digital I/O Module with 48 Digital Input Channels, a 100-pin keyed female SCSI I/O connector, and a Hybrid PXI Bus Connector. The NI 779949-01 is an industrial, parallel digital input interface suitable for various applications such as automotive design, industrial automation, machine control, aerospace, laboratory research, and biomedical applications. It features programmable power-up states, allowing you to set the initial output states in software for safe operation with industrial actuators.
If a computer or application defaults, this device uses digital I/O watchdogs to switch to a safe output state, ensuring fault detection and safe recovery. It also includes programmable input filters to eliminate glitches and spikes, providing debouncing for digital switches and relays through a software-selectable digital filter. The digital logic of the NI 779949-01 registers a logic low when no voltage is applied to the load and no current flows through the load or the module's input. It registers a logic high when it detects a closed switch position and current flows through both the device input and the load.
This digital I/O module requires a current of 250 mA at +5 VDC (±5%) and 400 mA at +3.3 VDC (±5%). Additionally, this device operates with the NIDAQmx driver software, which is compatible with software packages and application development environments (ADEs) like LabVIEW or LabWindows/CVI. You can verify the device using the Measurement & Automation Explorer (MAX) tool.
The 779949-01requires an input current of up to 3.0 mA per channel. It supports change detection with a minimum pulse width of 150 µs. The typical propagation delay is 65 µs, ensuring timely signal processing. For connectivity, the device uses a 100-pin keyed female SCSI connector.
