how to connect newport hp846 shutter with NI USB 6009

[fdfdf]

I need to communicate with NI USB 6009 and newport hp846 shutter using the DAQ assistant.Basically I need to give a command to the shutter to open and to close.

I have used the DAQ assistant before for very small projects,But in this case,I do not how to deal with this.thanks

You have not provided any of the necessary information in order to answer your question. What sort of signal does the shutter require?

A quick search of newport.com does not list an HP486 so attach a link or the actual data sheet.

I think,I need to give a voltage signal.I will attach the hp845 data sheet.hp846 is very much similar to that.I just need to open and close the shutters,that way I can use it

to my experiment.thanks

You will need to add a driver in between the digital output and the shutter control since the DIO is only capable of driving 5mA and you need at least 400mA

I have only the shutter and the NI6009.I do not have a shutter controller.I need to make a shutter controler by my self and it should take 

the voltage from the NI6009 and should work according to the labview program I write to the DAQ.

  can you tell me what should be the circuit I should make which can be communicated with the DAQ.thanks

can I have a comment please..thanks

You've got the 600x and LabVIEW. LabVIEW has DAQmx, with those VI's and the drivers you can command the 600x to do things.

The 600x has analog and digital I/O's. Those are spec'd in the manuals - things like voltage, current sinking/sourcing, timing... that's what you've got.

On the other side is your 846 shutter. Your datasheet for that doesn't have a lot of useful design information - a connector part number, pinout, and voltage/current requirements on those pins are what you're looking for. Might have to contact the manufacturer for those.

Your task lies in making the two (846 and 600x) "talk" to each other. Datasheets are your friends. You'll probably need either a driver or a relay to make things work right.

Sometimes shutter control is more complex if speed of response and repetition rate is of importance.

The nm Laser shutters I use for high power CO2 lasers have circuitry that drives the shutter with higher voltage than nominal at first for a fast closure. It then defaults to a much lower holding voltage to keep the blade open. The lower voltage also allows for a faster closing response. It may even apply a reverse bias, don't know for sure.

You may also need a reverse biased diode or snubber across your shutter coil to prevent damage to the driving device when power to the shutter is removed (back EMF). However, this can have contribute to a slower speed of response.

EDIT: I just found this, see section 3, it may give you a basis to go on for your unit:
