output (SPST-NO only for input).
• Ultra-slim housing measuring 29 (W) x 10 (D) x 32 (H) mm.
• All Output Relays provide a long endurance (1,000,000
operations at 5 A), while all Input Relays provide microswitching
power (100 μA at 1 V).
• Approved by UL and CSA standards.
Refer to Safety Precautions for All Relays.

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.
