Note: 1. When ordering, add the rated voltage to the model number. Rated voltages are given in the coil ratings table in
Specifications.

           2. The G7T-1122S and G7T-1112S are approved by UL and CSA. Contact your OMRON representative for the coil
ratings of other models. The G7T-112S cannot be used in place of the G7TC. The G7T-112S can only be used
with the P7TF-05 Socket.
3. “Input” and “output” indicate the I/O relationship to a PLC. Input Relays are mainly suitable for input signals to
a PLC or other device. Output Relays are mainly suitable to switching loads that receive output signals from a
PLC or other device. The Input and Output Relays have different switching performances. Select a suitable
Relay for the application.

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.
