PCI-1200: Product OverviewThe National Instruments PCI-1200 is a multifunction data acquisition board designed for PCI-based computer systems, providing a combination of analog input, analog output, digital I/O, and counter/timer functionality in a single device. This board belongs to the E Series DAQ product family, which represents a standardized platform for PC-based measurement and automation. The device serves as an interface between a host computer and external analog and digital signals, enabling applications ranging from laboratory measurements to industrial control.Installed in a standard PCI slot, the board operates as a measurement peripheral that converts real-world analog signals into digital data for computer processing and generates analog output signals for control applications. The analog input section features 16 single-ended or 8 differential input channels with a maximum sampling rate of 100 kS/s and 12-bit resolution. This configuration supports various signal levels from sensors and transducers commonly used in test and measurement applications. The board also includes two analog output channels, eight digital I/O lines, and two 24-bit counter/timers, providing a comprehensive solution for mixed-signal applications.The E Series platform provides a consistent architecture across multiple DAQ products, ensuring software compatibility and reducing development time when migrating between different performance levels or form factors. The platform’s standardized driver architecture supports multiple programming environments, allowing engineers to develop applications using familiar tools while maintaining hardware investment protection.

Core Features & Customer ValueIntegrated Multifunction Capability: The combination of analog input, analog output, digital I/O, and counter/timers on a single board provides a complete measurement solution for mixed-signal applications. This integration eliminates the need for multiple specialized boards, reducing system cost and complexity. For educational institutions and research laboratories, this versatility supports a wide range of experiments and measurements with a single hardware platform.Software-Configurable Input Ranges: The software-selectable input voltage ranges allow the board to accommodate various signal levels without hardware modifications. This flexibility enables direct interface with different types of sensors and signal sources, from high-voltage power monitoring to low-level transducer signals. The programmable gain amplifier optimizes measurement resolution for each input range, ensuring accurate signal acquisition across different measurement scenarios.E Series Platform Compatibility: As part of the E Series family, the board shares a common architecture and software interface with other devices in the series. This compatibility ensures that applications developed for one E Series device can be easily adapted to others with different performance characteristics or form factors. The consistent programming model reduces development time and protects software investments when upgrading or modifying measurement systems.Typical ApplicationsIn educational laboratory settings, the board interfaces with various sensors for physics and engineering experiments, measuring parameters such as temperature, pressure, and voltage while providing analog output for control experiments. The multifunction capability supports comprehensive laboratory exercises covering data acquisition fundamentals.For industrial monitoring applications, the analog inputs measure process variables from transducers while the digital I/O monitors equipment status and controls relays or indicators in small-scale automation systems. The counter/timers can measure frequency and period of signals for rotational speed monitoring or event counting.In research and development environments, the board performs component characterization and system testing where mixed-signal capability is required. The analog outputs generate test waveforms while the analog inputs measure device responses, supporting transfer function analysis and frequency response testing.
