Data acquisition output modules transfer amplified, conditioned, or digitized signals to processing systems or devices. They plug into backplanes or motherboards, or interface directly with computer buses. User interface features include touch screens or front panels and displays, handheld or remote programming units, and connections to supervisory or host computers. Some data acquisition output modules output ranges of voltage or current. Other devices transmit frequencies or pulse signals such as amplitude modulation (AM), frequency modulation (FM), or pulse width modulation (PWM). Timers, relays, switches, and potentiometers can also receive outputs. Optional features include random access memory (RAM), data storage, and configurable application software for real time graphing and mathematical or statistical functions. |
Products & Services Related to Data Acquisition Output Modules
Analog-to-Digital Converters
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.
Bridge Conditioners
Bridge conditioners are instruments that provide excitation and support for strain gages, Wheatstone bridges, load cells, and sensors. They also include circuitry for signal conditioning, amplification, and processing.
Data Acquisition
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.
Signal Filters
Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics.
Temperature Signal Conditioners
Temperature signal conditioners accept outputs from temperature measurement devices such as resistance temperature detectors (RTDs), thermocouples, and thermistors. They then filter, amplify, and/or convert these outputs to digital signals, or to levels suitable for digitization.
Voltage-to-Frequency Converters
Voltage-to-frequency converters accept a voltage signal and convert its analog level to a signal with a corresponding frequency.
