Sending 0-10v through a 0-5v I/o

From what i can see there is already a voltage divider in there? So if were to just go the resistor route, those 2 inside would be in series, so I would need to add a 20kohm outside between the input and ground?

Looks to me like that would do it.

Oh wait no i said that wrong, it needs to be be in series....

You are correct. I read what I wanted to read from your post. Not what you wrote.
Connect the resistor in series between the sensor and the input terminal.

Follow the advice of DanW in message #14. It's exactly spot-on for what you want to do.

Except that isn't the actual sensor Sprayman is using. Sprayman corrected that in post 15.

You are correct, I see that now.

You can actually get the precision 250 Ohm resistors on Amazon.
I use a lot of them...but you can find smaller quantity....

I use about 50/100 per month but I dont need .1%, 1% is good enough for me and mine are 1/4watt, I pay .13 each

1% IS probably good enough. I like Amazon cause it is so easy, just maybe a little more expensive.
The 250 OHM resistors supplied by Honeywell for their instrumentation and plc analog modules are .05%.
