Small I/O blocks for a tight spot??

[SteinCollector]

Looking for suggestions for very small remote I/O blocks -- 16 digital input/16 digital outputs. Still waiting on some dimensional specs for some bolts that will be screwed into the tray, but my space is limited to, say 2.5" wide, 3" deep , 6.5 - 7 inches long. Not concerned about the network used (Profibus, E/IP, etc) as I need to find a block that fits first, then work back from there.

I've read about Horner's Smartstix I/O - it seems to fit the bill (or tray) so to speak, but I'm not too familiar with them.

Any one have suggestions?

Yeah I also vote Beckhoff IO. We use them lots now, and they can interface into almost every network, and they wont cost you your first born.

I've fit the A-B CompactBlock and CompactBlock LDX into places that small, in the channel on the side of conveyors. DeviceNet, A-B RIO, and Profibus-DP.

Recently, I've seen some very small/tiny i/o blocks from Phoenix Contact connected via Profibus; sorry I don't have a part number.

What about the FDN20 or FDP20 stations from TURCK?

FDN20 Stations for DeviceNet

or

FDP20 Stations for ProfibusDP

Talk to your local TURCK Rep and he can sample you one to play with.

Thanks,

You could also try the VIPA 200 series, very compact but needs to be in a panel.
