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

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control. PACs are functionally similar to programmable logic controllers (PLC), but provide the advanced software features of personal computers (PC).

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

Programmable automation controller (PAC) systems consist of PAC modules, each of which performs a specific function. PAC systems are used in motion control, machine control, machine vision, and other industrial control applications

Remote terminal units (RTUs) connect directly to sensors, meters, dataloggers or process plants, and collect and transmit data automatically.

Microcontrollers (MCU) are complete computer systems on a chip. They combine an arithmetic logic unit (ALU), memory, timer/counters, serial port, input/output (I/O) ports and a clock oscillator

Communications and network software is used for the setup and management of digital communication networks such as LAN and WAN computer networks, electronic mail, FAX, audio and video networks, wireless communication systems, etc

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

Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems

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

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.

Charge and capacitive signal conditioning modules or systems amplify, attenuate, filter and/or convert a charge signal from an accelerometer, load cell, pressure transducer, displacement transducer or other type of capacitive sensor
