Hi, the 4-20mA to 5 V converter does not use any optical isolation (as far as I can see). Typical industrial PLC I/O's are mostly opto isolated for analog signals. Would that be a concern? Excellent channel btw!

You are correct. It also depend on the area and scale of application. I won't recommend it for use in safety critical equipment. For hazardous area application, an IS barrier can be an added protection.

I really like these videos! Is it possible to connect the 12 volt power supply together with the USB to my computer? I wrote software to read out the analog values on my computer but I don't know if it is safe to connect both USB and Vin pin. Thanks and keep up the good work!
@OnosTech

The 12 volt supply should go to the module alone. It is only the output and GND of the module that should be connected to the USB port of your computer. Just ensure that the output of the module is calibrated to 5 volts as demonstrated in the video.

Thank you for sharing this is very helpful, I'm testing this module with 4-20mA sensor and arduino uno, The reading are ok, voltage increases as the pressure in the sensor also increases, but in the readings with arduino a kind of noise is getting to the board, for example from when reading voltage 202 - 203, or when it raises to 205 - goes back to 202, and it is ramdom, What can I do, de arduino is powered with same 12vdc power supply as the module, and the sensor is with a 24vdc power supply. Thanks in advance!!

I am very sorry for replying late. The module power range is between 7 to 36V. Try any voltage within this range. If possible try to bring down the Arduino power supply voltage to a minimum of 6V and see how it goes.
@simonl7784

I'm trying to make sense of the "Current to Voltage Module" and I thought the whole point of it was to serve as the power supply to the sensor; which would explain the wide input 7-36v . Does it work if you just plug the temp sensor in without the 24v power supply?
@OnosTech
2 жыл бұрын
Sure, the module provides the loop power to the sensor and at the same time receives the measured values within the range of 4-20mA current. This current is then converted to 5 V which is the required input voltage of the Arduino analog input. The 24V power supply is required for the module and the sensor to work.

Can this module take an input voltage of 24V? My experience is that when I use 24V, the power indicator starts to flick very fast and slows down gradually. and the voltage output would become jumpy at the same time. is there any problem with this module using 24V?

There are actually two types of these modules; 1. s.click.aliexpress.com/e/_DEjqtG1 2. s.click.aliexpress.com/e/_AfeXw5 I actually used No, 1 in the tutorial video. I found out that at 24v, the transistor becomes hot. So I got No. 2 and used it in this other video with 24v: kzitem.info/news/bejne/0q6ZvIuOZnSiiKQ No. 2 works better. Which of the modules do you have?

Why not use a resistor and if you are worried a zener to clamp maximum? You don’t need a module to convert current to voltage.

That can also be done. But the purpose of the video is to minimize or eliminate soldering for those that cannot solder and to provide perspective on field instrumentation zero and span calibration.

I think, if resistor 250 ohm burnt out or connection loose at this point, microcontroller will get 24 VDC from sensor and make microcontroller burnt out too. SO this module may protect this issue.
