analog signal conditioner needed

Hi All,
I'm on the hunt for an analog signal conditioner that can do the following:

I have a 10k pot joystick that is spring-return-to-center. Thus, it will output approximately 5v when "centered." I need to take that signal and convert it to +/-10v to feed to a Baldor freq. drive for speed/direction control.

Essentially:
A) when the pot reads 10v, I need the signal conditioner to output +10v.
B) when the pot reads 5v, I need the signal conditioner to output 0v.
c)When the pot reads 0v, I need the signal conditioner to output -10v.

I've attached a schematic snippet for reference. I've Googled "signal conditioner" but with the thousands of hits, I'm a little buried, and I'm looking for something I can source pretty quickly. Anyone have a favorite make/model that will do what I need?


Thanks!

I'm not at a computer but I'm pretty sure you can get what you need at api-usa.com. Off the top of my head I think a 4300G can be configured that way.

phoenix contact and weidmueller make good ones, but im not sure about the -10v to +10v range.

The Omega.com model DRG-SC-DC-B signal conditioner ($319, din-rail mount, 24 VDC powered) has a 0-10 V input selection and a -10 to +10 volt output selection. Make sure to get the "bipolar" unit (B at end of model) so that you get the -10 to +10 output.

Why not just get another small 10VDC (12VDC adjustable) supply, and feed your pot from -10 to +10?

Use some resistors like 10k and 10 k the middle of them will be +12 volt.
This will be your ground.
As the pot will sweep now from -12 to +12 Volt you have to put some 1k resistors on the endings of it to get 10 Volts max.

Watch the current in your Pot 24 Volts over 12kohm is 2 mA is 0.05 Watt

Well, that's just a damn good idea! Forest for the trees... Thanks!
