●Installation Pitch and Output
Switching Capacity (Reference Val-
ues)
The relation between the installation pitch
and the load current is shown in the follow-
ing graph. (Except for the H3DK-GE)
If Timer is used under load conditions that
exceed the specified values, the tempera-
ture inside the Timer will increase, reducing
the life expectancy of internal parts.
* With the H3DK-M@, if the voltage exceeds 26.4 VAC/DC in mode C, D, or G, the OFF trigger signal char-
acteristics are as follows:
Accuracy of operating time: ±1% ±50 ms max.
Setting error: ±10% max.
Minimum input signal width: 100 ms
■Applicable standards
Accuracy of operating
time ±1% of FS max. (±1% ±10 ms max. at 1.2-s range)*
Setting error ±10% of FS ±0.05 s max.*
Minimum input signal
width 50 ms* (start input)
Influence of voltage ±0.5% of FS max. (±0.5% ±10 ms max. at 1.2-s range)
Influence of tempera-
ture ±2% of FS max. (±2% ±10 ms max. at 1.2-s range)
