3 / 9 page 3 G7Z Characteristics 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°C. *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°C. *5. The specifications for the auxiliary contact block mounted on the G7Z are the same as those for the G73Z auxiliary contact block. *6. The failure rate is based on an operating frequency of 1,800 operations/h.
