Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.
Data acquisition I/O modules or cards have both input and output functionality. Digital or discrete I/O modules include on-off signals used in communication, user interface, or control.
Data acquisition input modules accept sensor and other signal output for data acquisition systems. They may include signal conditioning prior to the analog-to-digital conversion stage.
Data acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.
Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC, but may also include real-time features such as monitors and alarms.
I/O Modules, I/O cards and I/O boards are used to accept data (input) from computers, sensors, transducers, PLCs, etc., and then distribute the data (output) to other devices in the system.
PCI products are devices that use the peripheral component interconnect (PCI) bus standard. PCI products include bridges, extenders, and power supplies. They also include bus interface, adapter, memory, mass storage, networking, and serial communications modules.
