13.10 Governor and AVR module GAM3.1
13.10.1 Governor and AVR module GAM3.1
This governor and AVR module has four relay outputs, two analogue outputs and a pulse width modulation output, and two analogue
inputs. These I/Os are configurable.
GAM3.1 also has terminals for analogue load sharing (future use).
