Converting low amperage signal to high current
Converting low amperage signal to high current
(OP)
Hello,
I'm doing some prototyping and I'm looking to use a 0-10V signal (10mA max) to control two different proportional solenoid valves.
The first is 0-5V, 0-.37A
the second is 0-24V, .092A
What would be the simpliest way to convert this signal? I'm just looking to do some prototyping so quick and dirty will get the job done.
Thanks in advance.

RE: Converting low amperage signal to high current
I'm trying to use a voltage signal to control the valve, I dont see how a power supply would work...unless the power supply could take my signal in volts and convert it to a certain amount of current output.
I was kinda hoping there'd be something off the shelf so I didn't have to go build a breadboard for this.

Check these: http://www.lynch.ca/11-LynchDDPD.htm or google "proportional valve driver" for many more suppliers.

nbucska's suggestion is probably the easiest to implement.

Those are good ideas but he is hoping there'd be something off the shelf so I didn't have to go build a breadboard for this so most of us were looking at ready-made solutions rather than build from scratch solutions.
Skogs,
Do you know of a supplier of cheap valve drivers? I know plenty of expensive ones! A source of cheaper ones would be useful.

Prop valve drivers are plenty. And they are being used. So, even if they seem expensive, they are the right price. They wouldn't sell if they weren't.
The OP said that he wanted OTS gear. A dedivated driver is as close as you can get - it IS OTS.
Remember, this is Eng-Tips. Questions asked are supposedly about engineering - not kitchen table experiments.

The proportional solenoid driver is exactly what I was looking for. Had no idea they existed...so I'm glad I asked.
I would run a power supply, but space is limited around the lab so I'd prefer something small and compact like the prop solenoid driver.
