Expansion Inputs

Most controllers do not possess enough base inputs to monitor all the alarms a large facility has. To increase the number of alarms that a controller can monitor, we provide a line of expansion input boards (also called alarm expansion boards) such as the AEB8, that can be installed in the controller to provide additional connections (expansion inputs) for alarms.

The points on the base Model 16 appear as expansion inputs.

This table describes each of the menu items and fields.
