About Data Acquisition I/O Modules

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. Data acquisition is the processing of multiple electrical or electronic inputs from devices such as sensors, timers, relays, and solid-state circuits for the purpose of monitoring, analyzing and/or controlling systems and processes. Device performance, analog outputs, form factor, computer bus, connection to host, and environmental parameters are all important specifications to consider when searching for data acquisition I/O modules.

Products & Services Related to Data Acquisition I/O Modules

Current Loop Converters

Current loop converters convert an analog or digital signal to a current loop output such as 4-20 mA or 0-20 mA.

Current-to-Voltage Converters

Current-to-voltage converters scale and convert current signal input to the desired output voltage range.

Data Acquisition Input Modules

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

Data acquisition output modules or cards transfer amplified, conditioned, or digitized signals.

LVDT and RVDT Signal Conditioners

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.

Signal Converters

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

Voltage Converters and Voltage Inverters

Voltage converters and voltage inverters accept voltage input and provide a scaled voltage output. Conversion types include scaling up a low-level signal, voltage doubling, and inversion (converting a positive voltage to negative and vice versa).
