HYSTHERESIS

Hystheresis

Block Screenshot

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

  • Use zero crossing: yes

    Select to enable zero crossing detection to detect switch-on and switch-off points.

    Properties : Type 'vec' of size 1

Default properties

  • always active: no

  • direct-feedthrough: yes

  • number/sizes of activation inputs: 0

  • number/sizes of activation outputs: 0

  • continuous-time state: no
