  • Introduction to the Two-Wire Transmitter and the 4-20mA Current Loop (.pdf)
    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?
    , 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 several advantages in industrial settings. This signal is not as susceptible to electrical interference from high voltage AC, motors, pumps
  • Monitoring and Controlling Solar Heating Systems
    including thermistors, pyranometer voltage, 4-20mA current loops, and pulse signals from the flow meters and energy meter. This device would also need to capture near real-time data snapshots for periodic monitoring during the day and also save historical data to an offsite location. A dataTaker DT80
  • Power Design Considerations For LED Applications
    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
  • Optimizing Production at a Mining Quarry
    and the throughput began appearing. To clarify this issue and to identify the cause of these discrepancies, an automated monitoring solution was required to monitor the conveyors' 4-20mA current loop on their belt scales to enable instant rate monitoring and view total tons of material moved per shift
  • Monitoring Temperature and Power on Aging 3-Phase Compressor Motors
    a particular period of time such as a day, week or month. 2 types of signals could be totalized: analog signals like a 4-20mA current loop, and digital signals from a switch or pulse output meter. The dataTaker provided built-in functions to automatically integrate measured values. Users could accumulate
