Bus Extender Unit
Module IOP371
Overview
The Bus Extender Unit (BEM) provides a flexible way to distribute the
system throughout the plant, resulting in reduced cabling costs and
installation time. Placing I/O in remote cabinets closer to a given process
typically reduces tray loading and the number of required junction boxes
since remote I/O cabinets are substituted. It also shortens wiring distances to
field devices, such as thermocouples and RTDs.
