Functional description
You can configure the pulse/interpulse width at the T
parameters.
Input Inv can be used to invert the output signal, provided the block is enabled with a signal at
input EN.
If the block is retentive, IDEC SmartRelay resets output Q and the expired time to the values
before a power failure; if the block is not retentive, IDEC SmartRelay resets output Q and the
expired time to defaults after a power failure.
