1. Rated current and coil resistance are values at coil temperature of 20, with tolerance of +15%/-20% for AC rated current.
Tolerance is 10% for DC coil resistance.
2. Maximum voltage is the maximum value of the allowable voltage fluctuation range of the relay coil operating power supply
with the ambient temperature at 20.
3. In the rated voltage of AC, </= (for example, 100/120) is a range rating and can be used in this range of voltage.
 The current values in the table are shown as typical values at 100V and 200V.
