Description
Switch output between two constants.The Relay block allows its output to switch between two specified values. When the relay is on, it remains on until the input drops below the value of the Switch off point parameter. When the relay is off, it remains off until the input exceeds the value of the Switch on point parameter. The block accepts one input and generates one output.
Dialog box
Switch on at
The Switch on point parameter is converted to the input data type offline using round-to-nearest and saturation.
Properties : Type 'vec' of size 1
Switch off at
The Switch off point parameter is converted to the input data type offline using round-to-nearest and saturation.
Properties : Type 'vec' of size 1
Output when on
The output when the relay is on.
Properties : Type 'vec' of size 1
Output when off
The output when the relay is off.
Properties : Type 'vec' of size 1
