} 2 logic inputs (AND/OR) for logic connections between several units
} Feedback loops for monitoring external contactors
} Detection of shorts across contacts via test pulse outputs
Safety features
The relay meets the following safety requirements:
} The circuit is redundant with built-in self-monitoring.
} The safety device remains effective in the case of a component failure.
} The safety outputs are tested periodically using an off-test.
