Coil Ratings (Common to Both Input and Output)

Rated voltage (V)		Rated current		Coil resistance	Must operate voltage	Must release voltage	Max. voltage	Power consumption
Rated voltage (V)		50 Hz	60 Hz	Coil resistance	Must operate voltage	Must release voltage	Max. voltage	Power consumption
AC	100/110	8.2/9 mA	7/7.7 mA	8,700 Ω	80% max. of rated value	30% min. of rated value	110% of rated value	0.7 VA
AC	200/220	4.1/4.5 mA	3.5/3.85 mA	33,300 Ω	80% max. of rated value	30% min. of rated value	110% of rated value	0.7 VA
DC	12	42 mA		290 Ω	80% max. of rated value	10% min. of rated value	110% of rated value	0.5 W
	24	21 mA		1,150 Ω	80% max. of rated value	10% min. of rated value	110% of rated value	0.5 W
	100/110	5 mA		20,000 Ω	80% max. of rated value	10% min. of rated value	110% of rated value	0.5 W

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.

Socket Ratings

Features

Easily mounts or dismounts the G7T I/O Relay.
Also mounts the Indicator Module (with surge suppressing function).
Only 19 mm in width.
Terminals corresponding to the NO and NC contacts of a Relay are arranged on top of the Socket to enhance maintainability.
Also permits mounting of the G3TA Solid-state I/O Relay.
