This linearized value is directed to output “rY“.If points “rX1” and “rY1” are identical (vertical characteristic curve), the output is setto 0. If the values “rY1” and “rY2” are identical, the output is set to the value of rY1 orrY2.YrY2rY1rXrXXSubject to design changes WAGO Kontakttechnik GmbH & Co.
