Probably, my request was not clear ... sorry.

In other words, my question is: if I've a -V option device connected to a I2C bus, the 12v (or more) power is mandatory, or the device can get power just from the I2C bus ?

The manual is not clear on this point.

Thanks, Stefano

Hi,

I'd like to use the LK202-25-V, the Extended Temperature option.

The question is, if the I2C +5V pin can be used to power up the device in place of use the normal power socket whit a 12V+

This becouse I ve both situation ... some place +5v ... some place +12v and and I'll use the I2C bus. So ...
