Design Schematic of I/O Circuit with complete Isolation circuit (Between DC 5V System and External Devices up to DC 60V)

Greetings, I am honoured to get this opportunity of being able to assist you in designing a circuit for interfacing between different voltage level signals. I am an electronics engineer have over 3 years of experience as a professional circuit designer and PCB design engineer. I have developed many systems based on Arduino and other controllers like STM, ESP and PIC etc. You can check my diversified portfolio at https://www.freelancer.com/u/nuamansaghir Interfacing between your logic board (most probably a controller based) and PLC is a relatively easy task but need to be very robust as there is a wide range of voltage at PLC end. I can take care of that very reliably and I will always respond earliest even after completion of this task. You can contact me anytime if need my assistance. I will provide you project files, gerber data for production and BOM as well. Let me know when may I start working on it? Looking forward to get your earliest response. Thanks in advance, Nuaman Saghir

I have more than 7 years experience in embedded hardware and software development . and i have already worked on opto electronics . So i can do your job within a time limit with your satisfaction.

Hello, I know exactly how to solve this problem because I am experienced with interfacing high voltage with low voltage devices like MCUs. I know how to do the calculations for the opto-coupler and the transistors for pull-up/down. Please contact me for more info.

Hai i read your project details I can support your project end to end solution without delay and without errors feel free contact me

hi..i have more than 8 years experienced in circuit design and development in my past i have designed plc io board for company..i can design best way without emiemc

I am a mechatronics engineer with 6 years of experience in the field of mechatronics and building projects. This is a familiar job for me and will get you a satisfactory solution within 2 days of time. I will forward my resume to you for higher confidence, it presents my accomplishments and experience in a detailed manner. Feel free to contact me.

I have experience of designing electronics circuits for about 10 years and i am very fluent with altium designer and kicad softwares. If you accept we can start on your project right away. Regards

Hello , i am electrical engineer , and i work very well and complete within 5 - 6 days. i have done PCB layout and circuit design training in college time. So i can do your job within a time limit with your satisfaction.

Will need the pcb or schematic to carry out the modifications in the circuit to suit it to interface it to external devices.

HI, I can help you in this design. I have experience is Electronics design. I clearly understands your requirement. I can design the I/Os based on optocouplers for higher voltages and current drives. I will consider proper protection of Photomos, EMI/EMC. The most important here is selection of Photomos and its biasing circuit for its long life. I fully aware of what to be considered for robust design. If models are available I can give you respective simulations too. Ping me for further discussion.

i had understand your project description as you might need a boost control from your low voltage microcontroller to a plc control (as a isolated driver) using an optocoupler yes i can assist and finish(including pcb design and 3d case for the pcb mount) your project as per the guidelines and description please ping me and we shall chat and discuss the details
