online data acquistion of voltage and current signals

[yasink]

What is the name and model of the NI instrument to measure the 3-phase 220V, 5A signals? Also, what will be the approximate cost of this equipment(s)?

Hello Yasink,

It sounds like you might be referencing the 5A Current Input Module with 250Vrms isolation, the NI 9227.

Can you provide more information on the desired application? From there I may be able to provide a better recommendation.

Thnaks for your reply message.

Actually, i want to record the online signals of the current and voltages of distribution system (11kV~37kV). Using CT/PT we can step down the current and voltage signals to some acceptable level (e.g. 250V & 5A).

Now, the question of availabilty of some suitable instrument with NI because most of the NI instruments measures low voltage and very low currents.

I'm happy to have been able to help.

If you can step down your voltage/current requirements as stated, it's likely there's an NI product available.
