  0 To 20 mA Receiver Using RCV42
  PDF, 26 Kb, 档案已发布: Sep 27, 2000
  Many industrial current-loop applications call for conversion of a 0 to 20mA input current into 0 to 5V output. The RCV420 is intended primarily as a complete solution for precise 4 to 20mA to 0 to 5V conversion. But, with the addition of one or two external 1% resistors, the RCV420 can also accurately convert a 0 to 20mA input into a 0 to 5V output.

  Input Overload Protection for the RCV420 4-20mA Current-Loop Receiver
  PDF, 31 Kb, 档案已发布: Sep 27, 2000
  Because of its immunity to noise, voltage drops, and line resistance the 4?20mA current loop has become the standard for analog signal transmission in the process control industry. The RCV420 is the first one-chip solution for converting a 4?20mA signal into a precision 0?5V output. Although the on-chip current sensing resistor is designed to tolerate moderate overloads, it can be damaged by large

  Isolation Amps Hike Accuracy and Reliability
  PDF, 94 Kb, 档案已发布: Oct 2, 2000
  Fault tolerance, transient protection, and interference rejection are valuable features that isolation amplifiers bring to critical circuitry. Two useful examples of how designers can employ isolation amplifiers to improve their systems? performance and reliability are process temperature controllers and electrocardiogram (ECG) amplifiers.

  Implementing a 4 mA to 20 mA Current Loop on TI DSPs
  PDF, 204 Kb, 档案已发布: Jan 5, 2004
  Use of 4-mA to 20-mA (4-20 mA) current loops has become the standard in the process-control industry due to their increased resistance to noise compared to voltage-modulated signals. TI digital signal processors (DSPs) increasingly are becoming the standard for microcontrollers in a control application. Therefore, an opportunity exists to connect the many sensors and electromechanical devices on t

  Single Supply 4-20mA Current Loop Receiver
  PDF, 29 Kb, 档案已发布: Sep 27, 2000
  Many industrial current-loop data acquisition systems operate on a 24V or 28V single supply. You can make a single-supply current loop receiver with the RCV420 by using its 10V reference as a pseudo ground. The RCV420 will convert a 4-20mA loop current into a 0 to 5V output voltage with no external components required. The current loop can be sourcing or sinking and can be referenced to either the

  IC Building Blocks Form Complete Isolated 4-20mA Current-Loop
  PDF, 72 Kb, 档案已发布: Sep 27, 2000
  Current loops have become the standard for signal transmission in the process control industry. Current loops are insensitive to noise and are immune to errors from line impedance. Adding isolation to the 4-20mA current loop protects system electronics from electrical noise and transients. It also allows transducers to be electrically separated by hundreds of volts.
