I wish to control a pneumatic proportional valve using the NI 9263 analogue voltage output module. The module can only supply 1 mA and the valve requires about 0 to 10 volt @ ~5 mA. I have considered using an OP amp in unity gain buffer. Any suggestions / circuit examples ?

We usually use an Analog Devices or Dataforth isolated 5B module 0-5Vdc input to 0-10VDC output. This seems to work nicely.
