Note: 1. The rated current and coil resistance values are measured at a coil temperature of 23°C. Tolerances of AC rated
              current are +15%, –20% and tolerances of coil resistance are ±15%.
           2. Four rated voltages or currents are available to single AC models used with the P7TF-05 Socket. Only three
                rated voltages or currents are available, however, when the Relay is used in place of the G7TC.
           3. The operating characteristics values are for a coil temperature of 23°C.
           4. The maximum voltage is one that is applicable to the Relay coil instantaneously at 23°C and not continuously.

Note: 1. The above values are all initial values.
           2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
           3. The operate and the release times were measured with the rated voltage imposed with any contact bounce
                 ignored at an ambient temperature of 23°C.
           4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used
                 for checking the dielectric strength.
           5. The electrical endurance was measured at an ambient temperature of 23°C.
           6. This value was measured at a switching frequency of 120 operations per minute.
