Can use the NI 2501 switches with the NI 4060 DMM to measure voltages of 100V?

I am designing a test stand and want to be able to read voltages up to 100
V on
the NI 4060 DMM card. I want to use the DMM card with a relay scanner, so
I
can measure multiple channels. The NI 2501 states that it has a maximum
working voltage of +/- 10 VDC from chassis ground. Does this mean that I
cannot use this card with the DMM card? If not, what would you recommend.

Hi ValproEngineer,

You do not need the NI 2501 to control the switches when using the NI4060.

Please confirm with NI support.

My mistake.

I was thinking NI 4021!

It was a bad day.

Dear Sir,

Thanks for using the Developer Exchange.

The NI-2501 can only handle signals in the +-10V Range and the NI-2503 signals in the 60 VDC and 30 VAC(RMS).

To use the NI-4060 card with a multiplexer the best option you have is the SCXI-1127 or the SCXI-1128 module. The SCXI-1127/1128 can assume multiple configurations:

2 Wire Mode - 32X1 Multiplexer
4 Wire Mode - 16X1 Multiplexer
1 Wire Mode - 62X1 Multiplexer

Also you can use the module in Matrix configuration (32X1, 8X4)

The SCXI-1127/1128 can also handle signal up to 300 VDC or Rms.

I would like to look for the suitable switches pair to the PXI-4060 to measure the voltages and current:

24VAC @ 6 Amp
36VAC
110VAC @ 2.5 Amp
110VAC @ 4 Amp
40VDC @ 3 Amp

Could I use the NI 2565 or the NI 2586 for the purpose. If this the case how to wire the general purpose switch module
to the DMM PXI-4060.
