Coil Ratings
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.
Contact Ratings
Relay
Note: The ratings for the auxiliary contact block mounted on the G7Z are the
same as those for the G73Z auxiliary contact block.
