| Industrial 4-20mA/ 0-10V Current & Voltage Sources |
|
|
For industrial process control instruments, analog 4-20 mA current loops are commonly used for analog signaling, with 4 mA representing the lowest
end of the range and 20 mA the highest. The key advantages of the current loop are that the accuracy of the signal is not affected by voltage drop
in the interconnecting wiring, and that the loop can supply operating power to the device. Even if there is significant electrical resistance in the line, the current loop transmitter will maintain the proper current, up to its maximum voltage capability. The live-zero represented by 4 mA allows
the receiving instrument to detect some failures of the loop, and also allows transmitter devices to be powered by the same current loop (called
two-wire transmitters). |

Such instruments are used to measure pressure, temperature, flow, pH or other process variables. A current loop can also be used to control a
valve positioner or other output actuator. An analog current loop can be converted to a voltage input with a precision resistor. Since input
terminals of instruments may have one side of the current loop input tied to the chassis ground (earth), analog isolators may be required when
connecting several instruments in series. |
