The FlexMatrix allows up to 16 inputs to be aggregated and conditioned for tripping or
auxiliary functions. Up to eight output signals can be derived from the input signals.
Outputs can be configured for latching (lockout) and can also have a programmable
pickup and dropout delay.
In a typical application, the FlexLogic operands from protection functions are assigned as
inputs to the FlexMatrix. Each output can be assigned to a specific task, such as tripping
the breaker or blocking a protection element.
