Hi everyone
I'm trying to convert 0-10 VDC TO 1-5 VDC :bullshit: the tricky part is the conversion 0v to 1v by using electronic circuit not using any type of controller.
Thanks for the help

using op-amps without any further circuit optimization:

This can be done passively, assuming the input/output impedance don't need to be excessively high/low.

Assuming you have a stable 5V voltage source, all that's required is three resistors, but more may be required to get convenient values.

The problem not solved because bias is not right with the desired signal it originally for prusser transducer replacement (0-10Vdc) replacing (1-5Vdc) the controller only can read (1-5Vdc)! If there are any ways to mapping this voltage actively or passively? :-// |O

It's not clear what you're trying to do.
Did you read the links I posted above?
If all you want to do is scale a 0V to 10V signal, to 1V to 5V and you have a stable 5V supply, then all you need are three resistors.

If you require a low output impedance, then add an op-amp buffer.
Here's a site which can calculate the resistor values. It also shows the op-amp buffer, which is only required if you need to drive a low impedance load.
