BusWorks® 900EN Series for low channel-count applications
Each inch-wide module has a direct network interface and processes I/O signals on up to twelve channels. This space-saving approach is very cost-effective for systems that need to add I/O channels at an existing control site or network to new remote sites.
i2o® Peer-to-Peer Communication
Input channels on one unit can write directly to output channels on another unit without a host controller in between.
