Local HMI

The LHMI uses rugged 7-inch high resolution color screen with

capacitive touch sensing technology. The user interface has

been carefully designed to offer the best situational awareness

to the user. Visualization of the primary process measurements,

events, alarms and switching objects’ statuses makes the local

interaction with the relay extremely easy and self-evident. The

LHMI provides a control point for the selected primary devices

via pop-up operator dialogs.

REX640 offers comprehensive base functionality. However, it is

possible to further adapt the product to meet special installation

needs by including any number of the available optional

application packages into a single REX640 relay. For the

selected application packages, the functionality can be

extended by including the related add-on package. The

REX640 connectivity package guides the engineer in optimizing

the application configuration and its performance.
