Function and purpose
The converter of direct current 4-20mA is used for measurement of constant current on 4-20mA from different sensors and converting data into the format of an IP monitoring system. The system interface allows you to assign the sensor and introduce the function data conversion.
...
If the 4-20mA sensor or transducer does not have a built-in sensor power supply or its power is insufficient to connect the sensor, use an external power supply. Analog The analog input of 4-20mA AIine2- passive. The connection diagram is shown below:
...
For example, we have a pressure sensor with a linear function. Let's take the pressure sensors sensor "PD-39 X low pressure" as an example.
...
Let's name the sensor: "Pressure".
Choose "current" for the "user-defined type".
We put this formula inside the field "Expression".
Press "Save" to save changes.
...
Inside our "system System tree" we shall see new changes for the sensor:

Example 2: Three current loop 4-20mA pressure transmitters are monitored by the Vutlan monitoring unit | Description |
|---|---|
 | Same logic as Example 1, but with an additional number of 4-20mA monitored sensors. |
