The National Instruments SCXI-1200 is a versatile data acquisition and control module designed to deliver comprehensive analog, digital, and timing I/O capabilities in industrial automation applications. Featuring a 12-bit resolution, this module operates similarly to a Lab-PC+ multifunction plug-in board and communicates with a host PC via parallel ports. The SCXI-1200 is equipped with eight single-ended analog input channels that can be configured as four differential channels, allowing for flexible data acquisition configurations. It supports three distinct input modes: referenced single-ended (RSE), non-referenced single-ended (NRSE), and differential (DIFF). Additionally, the module provides two single-ended analog output channels with selectable output voltage ranges of 0 V to 10 V or ±5 V.

Digital interaction is facilitated by 32 TTL-compatible digital I/O channels, enabling extensive control and monitoring capabilities. The SCXI-1200's design includes an overload protection system capable of withstanding ±42 V when powered on and ±15 V when powered off, ensuring durability in demanding environments. Parameters such as offset error before calibration are ±50 mV maximum, while after calibration this is improved to ±0.2 mV maximum. Gain error specifications stand at ±1% before calibration and ±0.004% after. The module's physical dimensions are 3.0 x 17.3 x 20.3 cm, and it is designed to operate effectively in a temperature range of 0° to 70° C, with a storage temperature capability of -55° to 150° C and a relative humidity tolerance of 5% to 90% (non-condensing).

For software integration, the SCXI-1200 operates seamlessly with the NI-DAQmx driver software, compatible with various application development environments (ADEs) such as LabVIEW and LabWindows/CVI. The module features both a 50-pin male ribbon-cable front connector and a 25-pin female Centronics type B rear connector, facilitating straightforward connectivity in system configurations. This product is backed by a three-year warranty, with user and maintenance manuals available for download.
