Signal converters are electronic devices that receive one type of signal and output another type of signal. Common features include filtering and amplification or attenuation. Integral filters allow some signal frequencies to pass while attenuating others. Integral amplifiers multiply signals to the matching scale of the input device. For signal reduction, amplifier gains or multiplication factors may be greater than one or fractional. Signal isolation can be achieved through optical isolation, magnetic induction, or the use of capacitors. Inputs for signal converters include AC and DC voltages, AC and DC currents, charges from piezoelectric devices, and frequencies and other specialized waveforms. Signal converters that include multiplexers can combine several AC or DC inputs serially into one output. |
Products & Services Related to Signal Converters
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.
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.
Frequency Converters and Translators
Frequency converters and translators scale and/or filter frequency inputs to produce outputs signals with frequencies that are a function of the inputs.
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.
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).
