  CONVENTIONS ON THE DIFFERENT LOGICAL STATES 
ON INPUT 
The high logic state is defined by the presence of a DC voltage between Umin and Umax. 
The low logic state is defined by an absence of voltage. 
 
O
N OUTPUT  
The high logic state is defined by a closed contact. 
The low logic state is defined by an open contact.
