Note 1. The rated current for AC is the value measured with a DC ammeter at 60Hz half-wave rectification.
Also, the rated voltage of AC100/(110)200/(220) is the value at AC100V and 200V.
Note 2. The rated current and coil resistance are the values when the coil temperature is +23℃, and the tolerance is AC rated current +15%,
-20%, DC coil resistance ±15%.
Note 3. AC coil resistance is a reference value.
Note 4. Operating characteristics are values when the coil temperature is +23℃.
Note 5. The maximum allowable voltage is the maximum value of the allowable voltage fluctuation range of the relay coil operating power supply, and
is the value at an ambient temperature of +23°C. Continuation is not allowed.
Note 6. The peak reverse voltage of the built-in diode is 1,000V.
In addition, some products have a built-in diode with a peak reverse voltage of 2,000V. (Model MK2KPD)
