Bus adapters connect peripherals to computers that do not provide native support for a peripheral's interface. Some bus adapters are housed in cables that connect one bus to another. Others are board-level cards, blades, or stand-alone units with interfaces and power supplies.

Analog-to-digital converters (ADC) sample an analog signal and convert it to a series of digital values to represent the signal to a computer processor

Digital-to-analog converters (DAC) transform a digital number into a corresponding analog voltage or current

Bus analyzers and bus exercisers are used to monitor and check the performance of a system bus.

General-purpose interface bus (GPIB) controllers and GPIB interface boards are devices that enable communications between GPIB buses and GPIB networks.

Network modems (modulators-demodulators) are devices or programs that allow computers to transmit data over telephone lines. They convert digital computer data to analog sound waves and then demodulate the carrier signals to decode the transmitted information

Bus expanders are computer boards or cable systems that connect to other interface boards, using only one I/O slot while remaining compliant with the bus standard.

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry.

Video processor boards are used to process video, medical imaging, automated optical inspection, and other related activities. They can be fitted with between one and a thousand digital signal processing (DSP) units in order to increase the computing power of the board.

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

AdvancedMC products are mezzanine cards (MC) that use a bus specification from the PCI Manufacturers Group (PICMG) for the telecom industry. AdvancedMC products offer advanced telecom features and hot-swap capabilities

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.

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.

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

Data acquisition computer boards are self-contained printed circuit boards that typically plug into the backplane, motherboard, or otherwise interface directly with the computer bus.
