Innovate LM-2 wideband inputs

Hi everyone, just a quick question about the innovate LM-2 Product. It is available in either single or dual channel versions. I just wanted to know if i brought the single channel version, does it have 2 wideband inputs or just the 1? Wondering if i could buy the single channel version and just buy a second UEGO sensor for dual inputs later on if required. Hope this makes some sense.

Cheers.

Just one.

Thanks for confirming
