Current loop converters receive signal inputs from devices such as sensors and produce analog outputs in the milliamp (mA) range. Typically, these outputs are standard current loops with ranges of 0 to 20 mA, 4 to 20 mA, or 0 to 50 mA. Current loop converters use optical isolation, capacitors, and magnetic induction to isolate loops of transmit and receive data. They use separate transmit (T+ and T-) and receive (R+ and R-) loops, each of which can be active or passive. Current loop converters are used in a variety of industries and applications, especially with computer peripherals. For example, RS232 connectors are current loop converters that connect printers to personal computers (PC) by using current on and current off communications to transmit binary digits. |
Products & Services Related to Current Loop Converters
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.
