1. Rated current and coil resistance are values at coil temperature of 20#, tolerance is 10%.
2. Operate voltage and release voltage are values at coil temperature of 20#.
3. 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#.
