Data acquisition computer boards are self-contained printed circuit boards (PCBs) that plug into backplanes and motherboards, or interface directly with computer buses. They receive multiple electrical or electronic inputs from devices such as sensors and translate analog data into a digital format that computers can process. Data acquisition computer boards are an integral part of data acquisition systems for monitoring, analyzing, and/or controlling systems and processes. These devices include random access memory (RAM) and can include software that supports real time graphing, mathematical functions such as averaging, and statistical calculations such as deviation.
