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.
