H3DK-M/H3DK-S
■ Timing Charts
• There is no start input with the H3DK-S. Timer operation starts when the power is turned ON.
• There is no instantaneous output with the H3DK-@1.

Note 1.The reset time is 0.1 s min. Make sure the signal input time is 0.05 s or longer.
Note 2.“t” is the set time. “t−a” is a time that is less that the set time.
