Note: 1. Rated current and coil resistance were measured at a coil temperature of 23°C with coil resistance of ±15%.
2. Operating characteristics were measured at a coil temperature of 23°C.
3. The maximum allowable voltage is the maximum value of the fluctuation range for the Relay coil operating
power supply and was measured at an ambient temperature of 23°C.
There is, however, no continuous allowance.

Note: The above values are initial values.
*1. The contact resistance for the Relay (G7Z) was measured with 1 A at 5 VDC using the voltage drop method.
The contact resistance for the auxiliary contact block (G73Z) was measured with 0.1 A at 5 VDC using the voltage
drop method.
*2. The operate time was measured with the rated voltage imposed with any contact bounce ignored at the ambient
temperature of 23℃.
*3. The insulation resistance was measured with a 1,000-VDC megohmmeter applied to the same places as those used
for checking the dielectric strength.
*4. The electrical endurance was measured at an ambient temperature of 23℃.
