  • Introduction to the Two-Wire Transmitter and the 4-20mA Current Loop
    . This paper reviews the operation of this transmission standard and. its advantages, in particular as it relates to two-wire transmitters and the associated 4-20mA current loop.

    zero" and an alarm condition. Some installations still use pneumatic control today. Modern I/P converters (current-to-pressure transducers) are available to convert the 4-20mA control loops to common pneumatic ranges, such as 3-15psi, 1-18psi, 3-27psi, and 6-30psi.
  • Programmable Current Loop
    The DACOUT of the FGD40xx can be used to design a programmable current loop from 4 to 20mA (4mA when DACOUT=0, 20mA when DACOUT=2.5V). The DC voltage output of the DACOUT has a voltage range of -2.500 to +2.500; for current sinking application 0 to +2.5V the design in Figure 2 can be used. For 0V
  • Application Note: Creating a 4-20 Ma Current Loop on the ACT-1B and ACT-3
    supply = (Rmax x 0.02) + 4. V supply should not exceed 40V. Where. Rmax is the maximum total loop resistance (except for the ACT). V supply is the Voltage for the power supply. 0.02 is the maximum current in the loop which is always 20mA.. 4 is the minimum voltage across the ACT where it can properly
  • Should You Use Current or Voltage in Analog Transducer Readings?
    it in an industrial environment. Even when using shielded wire, the signal is highly susceptible to interference from high voltage AC, motors, pumps, relays, etc. The signal is also susceptible to voltage drops on log runs of signal wire. DC Current (4-20mA). In contrast, a DC current loop offers
  • AN104 4-20 mA Transmitters
    volt FS device (20mA * 500Ω =10). voltages required and are energized from either a. and 0.5 mV represents an error of 0.005 %. local power source or the actual current loop. ! Supply voltage variations are reduced at any load by. ! Current conversion circuits establish the 4-20 mA. the same factor
  • Monitoring and Controlling Solar Heating Systems
    for performance tracking, and to monitor energy production for billing. To save on cost, the company wanted a single solution with flexibility to connect with many different sensor types including thermistors, pyranometer voltage, 4-20mA current loops, and pulse signals from the flow meters
  • Optimizing Production at a Mining Quarry
    the conveyors ' 4-20mA current loop on their belt scales to enable instant rate monitoring and view total tons of material moved per shift so that the actual stoppages could be identified against the manually reported stoppages to find exactly where and how the discrepancies occurred. Current
