Ratings / Operation Coil
- The rated current and coil resistance were measured at a coil temperature of 23°C with a coil resistance of ±15%.
- The operating characteristics were measured at a coil temperature of 23°C.
- 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.

Performance
- The values given above are initial values.
*1. Measurement conditions: The contact resistance for the relay (G7Z) was measured with 1 A at 5 V DC using the voltage drop method. G73Z auxiliary Contact block: measured with 0.1 A at 5 VDC using the voltage drop method.
* 2. Measured with the rated voltage applied with any contact bounce ignored and at an ambient temperature of 23°C.
* 3. Measured with a 1,000 V DC ohmmeter at the same places that the dielectric strength was checked.
* 4. Ambient temperature: +23°C
*5. This value was measured at a switching frequency of 1,800 operations/hr.
* 6. The performance of the auxiliary contact block mounted on the G7Z is the same as that for the G73Z auxiliary contact block.
