*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 the value after the Timer times out.
