0-10v to 4-20ma converter circuit




















The controller receives a current from the sensor, allowing the Arduino PLC to transform that electrical signal to an understandable value. This value is used for the programmer to know the right units of measure received from that sensor and understand the Industrial project's situation. Arduino is not able to receive a current analog signal because the analog signals from Arduino work from 0 to 5Vdc, so it is necessary to convert the current analog signal to a Voltage.

It is important to know that Industry voltage analog signal standards work from 0 to 10Vdc so the way to transform a mA to Arduino is quite different as transformed for Arduino-based PLC which works at Vdc. It is necessary to convert a mA to a Vdc signal. As you can see in the below diagram, you can understand how to transform a mA to v using Ohm Law. To do this it is necessary to connect an impedance of Ohm between the analog mA signal and the ground signal as shown in the diagram.

If you do, the analog value will change from current to Voltage. Arduino as a single board is not able to be used in Industrial environments for that reason Industrial Shields has developed an Industrial Shield for Arduino which includes an original Arduino board inside and it is fully compatible with Industrial Standards. It is easy to understand how to transform a mA to Vdc through a Ohm resistance through the Ohm Law.

Industrial Shields boards. To learn how to install the boards, click here. But, if you convert this signal to Vdc, the results are:. As you can see the result of 4mA 2Vdc , is close to Below is the linear graph where the results come from:.

Just fill the form! What is a mA Signal. Why is mA standard? Converter circuit diagram for mA Analog Sensor to Vdc. How can you make a mA to V signal conversion on your industrial controller Arduino for industrial automation? You can use Arduino based PLCs Arduino as a single board is not able to be used in Industrial environments for that reason Industrial Shields has developed an Industrial Shield for Arduino which includes an original Arduino board inside and it is fully compatible with Industrial Standards.

If you have not used Arduino IDE before you can also join the course. Common transmitters or sensors use one or more of the above formats to output standard signals. Common secondary meters or acquisition cards generally accept input signals of one or more of the above formats. When the output signal of the transmitter or sensor is different from the input signal format of the secondary instrument or acquisition card, we need to add a converter between them.

Because the mA standard signal has the advantages of strong anti-interference ability and no attenuation in the transmission process, it has been widely used in the field of measurement and control. Often in order to achieve interface compatibility or improve electromagnetic compatibility, it is necessary to convert V, V and other standard voltage signals into mA standard current signals.

Or the mA current signal needs to be converted into a V or V standard voltage signal suitable for the input of the acquisition card. I have a pressure transmitter here that outputs a current of mA.

As the input signal of the inverter. Now it is required to change the input signal of the inverter to a voltage signal. That is, the current of mA should be replaced with a voltage of V or V. The inverter has two inputs: V and V. Excuse me, how can it be transformed? Use a hardware circuit to convert the input mA current signal into V or V voltage signal.

See the circuit diagram below:. The signal converter converts the DC current or voltage signals of various devices on the site into the required DC signals for isolation and transmission and then outputs them to other instruments. The signal isolator can effectively eliminate ground return. Solve the problems of industrial field interference and signal conversion, transmission, and matching.

It is widely used in data acquisition, signal transmission and conversion, PLC, DCS, and other industrial measurement and control systems in electrical, power, telecommunications, steel, petrochemical, sewage treatment, environmental protection engineering, aerospace, building automation, and other fields. Increase The applicability of the system and the reliability of the on-site environment. Request a Quote. Your email address will not be published. Contact US. What is a mA Signal?

What is the difference between mA and 0 10V? But maintenance measurement is more troublesome; ma DC signal can provide power. In addition, it is not affected by the load size within a certain range, and has strong anti-interference ability.
