Definition

When the relay is triggered, the state is retained by a function called a self-holding circuit. For the 61F-GN Level Controller, electrode E2 is the self-holding circuit. A self-holding circuit enables a control range to be set and also prevents the relay from switching rapidly due to ripples on the liquid surface.
