Specifications

Ratings

Coil

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 ratings for the auxiliary contact block mounted on the G7Z

are the same as those for the G73Z auxiliary contact block.
