Calculating Input Current

Hello,

I am stuck with one simple question.

IB16M12SOEDR,
current, on-state input, max = 5 mA @ 30 VDC
I have a proximity sensor that 10 mA @ 24 VDC to power itself.

While working on power calculation for this channel,
should I consider 10 mA + 5 mA or is it just 10 mA?

This is confusing the hell out of me.
