i need to get a 12 volt output from NI in varying pulse width so what daq should i use to get 12 volt and how can i get pulse voltage...?

Hi Kishore,

You can use high switching frequency relay where relay comman should connect to 12vDC and coil should be connected to DAQ where you will genarate vriable pulse output. At Normaly Open(NO) of relay you will get 12VDC pulse.
