When using a 24-VDC power supply voltage,
there will be an inrush current of approximately
0.5 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.

DC ripple: 20% max.
*3.
The power consumption is for after the Timer
times out in mode F2 for the H3DT-N and
mode A for the H3DT-L.
The maximum power consumption is given,
including the current consumed by the input
circuit.

Relation between H3DT Ambient
Temperature and Mounting
Interval (Reference Values)
The relation between the ambient temperature
and mounting interval is shown in the following
graph.
If the Timer is used at 55°C or higher with a
mounting interval that is smaller than that
shown in the following diagram, the
temperature inside the Timer will increase,
reducing the life expectancy of internal parts.
