*1. When timer operation is started by power application. This does not apply to the H5CN-X[]NM. The H5CN-X[]NM
       cannot be reset by tuning OFF the power.
*2. When timer operation is started after a reset input has been applied.
*3. These values represent the total accuracy of the timer including the repeat accuracy, setting error, and variation due
       to voltage and temperature changes. Note that they also comprise errors due to the rise time of the power source
       and the operating times of the internal and output circuits.
*4. This applies only to the H5CN-X[]NM.

Life-test Curve (Reference Values)

H5CN Specifications 8

A maximum current of 0.15A can be switched at 125 VDC (cosφ = 1)
Maximum current of 0.1 A can be switched if L/R is 7 ms. In both cases, a life of 100,000 operations can be expected. The minimum applicable load is 10 mA at 5 VDC (failure level: P reference value).
