*1. When using a 24-VDC power supply voltage, there will be an inrush current of approximately 0.25 A. Allow for this
inrush current when turning ON and OFF the power supply to the Timer with device with a solid-state output, such
as a sensor.
*2. DC ripple: 20% max.
*3. Refer to DC Power Consumptions (Reference Information) on Catalog for DC power consumptions.
*4. The control output ratings are for one H3DK operating alone. If you operate two or more Timers side by side, refer
to Installation Pitch and Output Switching Capacity (Reference Values) on the Catalog.
*5. For the H3DK-GE, approx. 6 A of inrush current will flow when the power supply is turned ON. When selecting the
device connected to the Timer, allow leeway in the current ratings.

Installation Pitch and Output Switching Capacity (Reference Values)
The relation between the installation pitch and the load current is shown in the following graph. (Except for the H3DK-GE)
If Timer is used under load conditions that exceed the specified values, the temperature inside the Timer will increase, reducing the life expectancy of internal parts.
