Title: Nano-10 on 12V
Post by: kparson on January 31, 2013, 10:42:25 PM

Has anyone run the Nano-10 on 12V?  Is so, any issues I should know about?

I think the may actually run at 12v, but you may not be able to use the relays (outputs 3&4).  I discovered this when my battery went so low that the 12 to 24v converter couldn't make more than 12 volts.

That is correct. You would not be able to use the relay outputs.

The Nano-10 is technically rated for 24VDC only; however, it can actually be run on 12VDC if you have no other option but is subject to the following conditions:

1) Outputs 3 & 4 (relays) will not work, so only outputs 1 & 2 are available.

2) The PLC cannot implement the power failure interrupt. (PFI occurs at around 15 to 17V, so it won't work). This is a special type of Interrupt described in the Interrupts section of the Nano-10 user manual.
