Analog I/O devices process analog signals (e.g., output of transducers) and output the results in analog format.
|
|
Backplanes are circuit boards that contain sockets or expansion slots for connections to other circuit boards. There two types of backplanes: active and passive.
|
|
Computers are programmable electronic devices that accept data, execute prerecorded instructions, perform mathematical and logical operations, and output results.
|

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.
|
|
Digital I/O devices process digital signals (e.g., outputs from a controller) and output the results in digital format.
|
|
Digital signal processor (DSP) computer boards are central to the implementation of high-performance industrial systems. They collect and process digital data from many sources, and distribute the results to other elements of the system.
|
|
Electronic enclosures and instrument enclosures house electronic components and instruments. They are usually designed for handheld or desktop applications.
|
|
Flat panel displays (FPDs) are thin, flat, electronic devices used to display data. They are commonly used in notebook computers. Most styles include the housing and ports necessary to connect them to a computer.
|
|
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.
|
|
Industrial chassis and card cages are metal frames that support and contain electronic components and power supplies. They generally have a backplane with slots to install other peripherals and accessories.
|
|
Industrial computer monitors are ruggedized for use in control room, factory floor, or process applications.
|
|
Industrial computers are similar to personal computers (PC), but they are intended for use on a factory floor or in other harsh environments.
|
|
Industrial enclosures are used to house electronic components, equipment and devices. They are designed to protect personnel from accidental injury and to prevent the ingress of environmental contaminants.
|
|
Industrial keyboards are peripheral hardware devices that include alphanumeric keys, electromechanical buttons, or sensors that users press to interface with a computer.
|
|
Liquid crystal display (LCD) modules are used at the component level in place of less efficient displays such as cathode ray tubes (CRTs). These modules do not include a housing and must be incorporated into a larger instrument or system.
|
|
PC/104 modules are tied to the integrated system architecture (ISA) bus standard that is used mainly in embedded systems. Modules are 3.6" x 3.8" and can be self-stacked to save space.
|
|
Single board computers (SBC) serve as the motherboard for instrumentation systems including modern PCs. SBCs are composed of a microprocessor, memory chip, and serial and parallel interfaces to communicate with other devices.
|
|
Standard keypads are standard size membrane or carbon pill keypads.
|
|
Switches are used to allow electric current to flow when closed. When opened, they prevent current flow. Common switch types include pushbutton, rocker, toggle, rotary coded DIP, rotary DIP, key lock, slide, snap action, and reed.
|
|
Terminal and junction boxes are used to house electrical components and facilitate wiring. They are T-shaped or rectangular, made from a variety of materials, and available in many different sizes, sealing configurations and mounting styles.
|
|
Touch screen displays are user-friendly input devices. The user touches the screen and the input is communicated directly to the computer.
