Good day, I can design 4-20mA signal isolation circuit in a quality and timely manner. I can provide 4-20mA signal coming from the sensors and sampling by an ESP32. Please share more details about this project. I would like to have a thorough discussion on this project as there are certain suggestions from my side After dedicating more than 30 years to the electronics design and development, I am passionate in designing the best products Technology wise I have worked on all the latest technologies like GSM, 5G, Lora, 4-20mA, ESP32 etc And have worked on more than 20 design tools for designing and simulation purpose Some of the generic queries from my side are: 1. What is the application of this product? 2. What will be the ambient temperature of this product? 3. What are the mechanical constraints to be taken care of? If you are someone who wants to benefit from my experience just message me Hi and I shall be there for you Regards Hari Mohan Engineering for one is magic for others

Hello, Thanks for posting the project. I am an Electrical Engineer with 30 years’ experience of Customized Product Development for Instrumentation and Control applications. I am based in Kolkata (India) and running a business in the name of "Zetek Systems". I have a good hardware setup and a team for fabrication and testing. I will give you a circuit where the an analog voltage is produced from input 4-20mA current. This output analog voltage will be galvanically isolated from the input. Looking forward to your valued reply. Regards - Debasis Basu

HELLO THERE; I am working as a research and development manager in a private company. I have more than 5 years of experience in embedded system software and hardware. As for software, I am proficient in microcontrollers such as (*****STM32*****), MICROCHIP, NUVOTON, ARDUINO, ESP32, MSP430, RASPBERRY PI. I have experience in communication protocols such as CanBus, ModBus, RS232, RS485, TCP IP, Socket Communication. I am an expert in Altium and KiCad programs in hardware. I have read and understood your project. I have realized isolated 4-20mA input and Outpu board many times before and I have reference designs. I can manufacture and test the card for you. Of course, you have to pay the material and card costs. Please write to me for details.

@mahmoudralizadeh

Hi I have done similar project of yours i can help you in your project In which part of the line you want the isolation? I'm an electrical engineer with expert in microcotrollers and circuit design Thanks

@GHOZLANI

Hello there! I see you are looking for someone who can design your isolation circuit interface between a 4-20mA output from a sensor and an analog input of an ESP32. Actually you need a circuit that converts the 4-20mA to a voltage signal, for example 1-3.3V, and then you can measure your signal as the ESP32 and all the microcontrollers can't measure current, so we have to to use a voltage signal as image of the 4-20mA current signal. I'm a circuit and PCB designer with eight years of experience helping companies and individual clients to make their own designs and i would like to help you out as well, so please allow me to have an interview with you to discuss more about your project, and thank you for your consideration. Have a great day.

@ahmadbhatti24

Hi, I hope you are doing well. Firstly i will request you to check my portfolio where i controlled alot of sensor by esp and arduino. But here you need 4-20ma signal that will come from the sensor and need to read and sampling on esp32 right? Just ping me back in chatbox for little bit more discussion and give me ok signal to start this task Im looking forward to make a good relationship with you. Thanks Engr Ahmad Ali

@lamhan18082003

Most industrial circuits use the 4-20mA standard for signal transmission, and this signal is very sensitive to noise. We need to isolate both signal and source to make sure. Luckily I already made this circuit and I can share it with you after we discuss the details! Message me to exchange first and the decision is up to you!

@djalltra

Hello sir,I've also faced problems on how to isolate signals from each other in some circuits but I have a very efficient approach I use and it works very well and it very cost effective. I am available for further discussions. Thank you.

@indrajeet9497

I COMPLETE THIS PROJECT WITHIN 10 DAYS AND ALSO PROVIDE AUTOCAD DRAWING FOR EASILY UNDERSTAND HOW CIRCUIT WORK.

@stairovic940

Hi, client! First of all, I am very interested in 4-20mA signal isolation circuit. My point is that I mastered Microcontroller, Electrical Engineering, Electronics, Analog Electronics and Analog / Mixed Signal / Digital with rich experience of 8 years in software development field. Here is the desktop app very experienced developer who mastered C++, C#, Python, Qt, VB.NET, WPF, UWP and electron. I took part in many C#, Unity and Games projects so I could gain deep knowledge about the C# and game logic with strong .NET skills. As a senior full-stack developer, I have been working with many languages and frameworks for build the desktop app associated with business logic and management system. Especially, C# and Python are my expertise and I have ever created the PLC ladder IDE from scratch. I worked in various filed in eCommerce, LMS, Insurance Sass, and so on In terms of DB, I mastered SQL server, PostgreSQL, MySQL, MongoDB and so on. I majored in computer science and devices so I have rich experience in PLC, ARM, VHDL, IoT and IoB. Based on this strong background knowledge about the devices, I built many high performance compilers such as PLC ladder IDE with many high performance and smart algorithm. So, I can handle any type for project in enterprise desktop app and HMI for IoT or other devices. Looking forward to hearing from you and I will provide you the best services. Please contact me.
