Retentive time
Set value
When the drive input X000 of the timer T200
turns ON, the current value counter for T200
adds and counts clock pulses of 10 ms. When
the count value becomes equivalent to the set
value K123, the output contact of the timer turns
ON.
In other words, the output contact turns ON 1.23
seconds after the coil is driven.
When the drive input X000 turns OFF or when
the power is turned OFF, the timer is reset and
the output contact turns OFF.

When the drive input X001 of the timer T250
turns ON, the current value counter for T250
adds and counts clock pulses of 100 ms. When
the count value becomes equivalent to the set
value K345, the output contact of the timer turns
ON.
Even if the drive input X001 turns OFF or if the
power is turned OFF during counting, the timer
continues counting when the operation restarts.
The retentive operating time is 34.5 seconds.
