The NI Lab-PC is a multifunction I/O board for ISA bus systems, integrating analog acquisition, analog output, digital I/O, and counter/timer functions on a single card. Designed for laboratory and industrial data acquisition applications, it delivers 12-bit resolution across both input and output channels with software-configurable voltage ranges and programmable gain amplification. The board supports continuous single-channel and multichannel scanning modes with hardware triggering, making it suitable for signal analysis, data logging, chromatography, and precision temperature monitoring.
