Convert a CT AC output to 0-5 Volt DC or 0-10 Volt DC output.

$15-25 USD / hour

Need 100 small circuit boards built to convert the output from a CR Magnetics CR3110 AC output to 0-5 Volt DC or 0-10 Volt DC. High accuracy is not critical since the signal can be curve fit in the PLC. Miniature components is important so everything can fit on a board .875 X 1.125 inch. Data Sheet attached. I am open to a different sensing element. Need a way to measure 0-75 amps and get the signal into a PLC. Again, high accuracy is not critical. A reasonable price is more critical. I am open to other pricing arrangements. Fixed price - higher hourly rate if your experience makes you efficient.

Hello, Greetings of Peace! I have been developing industrial applications from a long time. I have great hold on industrial interfaces including 4-20mA, 0-10V, 0-5V... Please check my portfolio. Please check the entry named "Data acquisition system" in my portfolio which has this interface. Also i have a setup where i can give you all the solutions from prototyping to manufacturing... As this is for CT, I will design a custom circuit which will read the CT input and convert it to 0-10V output... I can surely deliver you the best optimised solution for this. Please get in touch to discuss in detail. Best Regards, Bk Krunal

Hello, I am a experienced pcb designer, particularly in bldc motor controllers. These often require current measurements at their phases and is therefore closely relatable to your project. I have excellent suppliers and facilities to produce your required 100 boards effectively. I would charge $950 for the design work and 100 fully assembled circuits. It is a very interesting project and I look forward to hearing from you. Kind regards, Hugo
