*1. 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.
*2. 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.
