Input Delays
ON Delay
An input signal is treated as being OFF during the ON delay setting time (0 to 126 ms,
in increments of 6 ms) after the input contact’s rising edge. The input will turn ON only if
the input contact remains ON after the ON delay time has elapsed. This helps prevent
chattering of the input contacts.
