Analog I/O Information on GlobalSpec

Analog I/O devices process analog signals (e.g., output of transducers) and output the results in analog format. There are several types of analog I/O devices. Examples include analog modules, analog I/O boards, analog I/O cards, analog input cards, analog output cards, and USB analog I/O. An analog I/O device is a device that supports both analog input and analog output. Analog I/O modules are available in different models that provide eight channels of line-level analog to digital conversion and also eight channels of line-level digital to analog conversion. An analog I/O board allows the data acquisition system to record analog signals from any instrument and it generates the analog signals for any instrument. An analog I/O card is the circuit on a printed circuit board (PCB) that is capable of supporting both the analog input as well as output. An analog I/O card is analog output card which is used in applications where the outputs other than on and off states are generated. A USB analog I/O is a device that is used to interface a PC with a number of real world analog inputs or outputs.

Signal Amplifiers

Signal amplifiers accept signals from sensors and other devices and amplify them to levels suitable for further processing or digitization by computer elements.

Signal Conditioners

Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.

Signal Converters

Signal converters contain inputs for one type of signal and outputs of another. Features can also include filtering and amplification or attenuation.

Signal Filters

Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics.

Signal Isolators

Signal isolators must be used when connecting grounded signal sources to grounded signal followers. If the speed control input of an adjustable frequency drive is grounded, any input signal must be ungrounded.
