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

Digital I/O devices process digital signals (e.g., outputs from a controller) and output the results in digital format

Analog I/O devices process analog signals (e.g., output of transducers) and output the results in analog format

I/O Modules, cards and 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

Fieldbus industrial communications computer boards are used to control of sensors and actuators in industrial applications, such as data acquisition and control

PCMCIA cards and accessories follow standards developed by the Personal Computer Memory Card International Association (PCMCIA), an international standards body and trade organization. PCMCIA cards, or PC cards as they are commonly known, were designed originally for adding memory to portable computers, but are now used in a variety of devices.

IndustryPack^® modules are computer boards that interface with the IndustryPack (IP) mezzanine bus, a device used to provide input/output (I/O) capabilities in general-purpose computer systems. IndustryPack is a registered trademark of GreenSpring computers and a specification maintained by the VITA standards organization (VSO) of the American National Standards Institute (ANSI

Data storage systems are used to store, protect and manage computer data. Many types of disk drives and tape drives are available.

pH and ORP controllers monitor and can control the pH (acidity or alkalinity) and/or the ORP (oxidation reduction potential) of liquids involved in a testing or process application.

Encoder and resolver signal conditioners accept encoder and resolver measurements and convert or condition these signals into digital data or suitable levels. 

Delay lines are devices used to slow down a signal by a time interval in an electrical network. There are two basic delay line technologies: passive and active. 

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

Audio mixers and consoles are units that combine signals from microphones and/or line level sources to produce a combined signal or signals.

Industrial computer monitors are ruggedized for use in control room, factory floor, or process applications.

Linear variable differential transformer (LVDT) and rotary variable differential transformer (RVDT) signal conditioners are devices that translate the linear or rotary movement of a ferromagnetic armature into an AC voltage that is proportional to the armature position.
