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 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 output modules or cards transfer amplified, conditioned, or digitized signals.
|
|
Distributed and supervisory control systems (DCS / SCADA) are system architectures for process control applications.
|
|
Encoder and resolver signal conditioners accept encoder and resolver measurements and convert or condition these signals into digital data or suitable levels.
|
|
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.
|
|
Handheld computers are portable devices including notebook and subnotebook computers, palmtops, and PDAs.
|
|
Human machine interfaces (HMI) are operator interface terminals with which users interact in order to control other devices.
|
|
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.
|
|
Memory cards are computer chips used to add memory to a computer.
|
|
Network cards and network controllers are expansion boards inserted into computers that allow them to connect to a network.
|
|
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.
|
|
PCMCIA memory and storage cards (also known as PC cards) are devices used to add memory (RAM, SRAM, Flash, etc.) and/or storage capacity (hard disks, CD-ROM, etc.) to computers.
|
|
Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability.
|
|
Remote terminal units (RTUs) connect directly to sensors, meters, dataloggers or process plants, and collect and transmit data automatically.
|
|
Serial communication adapters provide one or more serial ports to a host computer. They interface with the host computer via a data bus and add RS232, RS422, RS485 and/or other types of serial ports.
|
|
Serial communication products are used in industrial and commercial systems to transmit data bit-by-bit, or sequentially, over a single wire. They include serial servers, serial hubs, serial adapters, serial data converters, serial routers, and serial multiplexers.
|
|
Serial industrial communications computer boards are boards or ports that transmit data by sending the bits one after the other over a single wire.
|
|
Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
|
|
Solid state relays or semiconductor relays (also called SSRs) can be used in place of mechanical relays to switch electricity to a load in many applications.
|
|
Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values.
