The controller can use relay outputs for many purposes. Examples: Activate alarm devices, open and close breakers, and genset

speed and voltage regulation.

Configuration

All relay outputs are configurable, except for PSM3.1 terminals 3,4 (Status OK), GAM3.2 terminals 14,15 (GAM3.2 1 Status OK),

and the DU 300 relays. A controller can have a number of relay outputs.

You can assign a digital output function or an alarm for a relay output.

You can also create customised digital output functions using CustomLogic, and assign a relay output.

Controller types and single-line diagram

The controller type determines which digital output functions are available.
