The NI DAQCard-500 is a 12-bit multifunction I/O card designed for portable and legacy data acquisition systems. This PCMCIA Type II card delivers analog input, digital I/O, and timing capabilities in a compact form factor, making it ideal for measurement and control applications requiring field portability or integration into existing embedded platforms.
Technical Specifications
Analog Input
• 8 single-ended channels
• 12-bit resolution
• 50 kS/s maximum sampling rate
• Successive approximation ADC architecture
• 1 GΩ input impedance in parallel with 40 pF
Digital I/O
• 8 TTL digital I/O lines
• 5 V/TTL compatibility
• Gate and source pulled high with 100 kΩ resistors
Counter/Timers
• 3 timing I/O channels
• 16-bit resolution
• 10 MHz maximum source frequency
Power & Interface
• +5 VDC @ 500 mA available at I/O connector
• 27-pin male connector
• 16-sample input FIFO buffer
• Slave-type bus interface
– Key Features
The card’s 16-bit counter/timers enable precise frequency measurement and pulse generation up to 10 MHz. Low power consumption with standby mode extends battery life in portable systems. The 16-sample FIFO buffer minimizes data loss during burst acquisition. No analog output channels are provided.
– Typical Applications
Ideal for legacy system upgrades, portable measurement platforms, and embedded control tasks requiring moderate channel density and sampling rates. Temperature monitoring, process control, sensor logging, and equipment diagnostics benefit from the combination of analog and digital I/O.
– Compatibility & Integration
Supports Windows operating systems (Part 777086-01) and Mac OS (Part 777086-02) through NI-DAQmx Base 3.x or later. Compatible with LabVIEW, LabWindows/CVI, Lookout, and VirtualBench. Integrates with LabVIEW systems built before 2015. Requires the CB-27 Terminal Block and PR27-30F cable (Part 777131-01) for full connectivity.
