Siemens 7SJ85 - Settings

You can use the Dropout delay parameter ≠ 0 s to obtain a uniform dropout behavior if you use it
together with an electromechanical relay. This is required for time grading. The dropout time of the electro-
mechanical relay must be known for this purpose. Subtract the dropout time of your own device (see Tech-
nical Data) and set the result.
