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.
