Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of 15%/
-20% for AC rated current and ±15% for coil resistance.
2. The operating characteristics are measured at a coil temperature of 23°C.
3. The value for maximum voltage is the maximum value within the allowable voltage fluctuation range for the
relay coil’s operating power supply. Continuous operation at this voltage is not within product specifications.
4. Approx. 4 mA flows into each LED indicator. To calculate the power supply capacity, add the current value of
each LED indicator.
5. When the G7TC is used with an AC rated voltage, three rated currents can be used. If a coil voltage of 110 or
220 VAC is used, 50 Hz cannot be used.

Socket

P7TF-05
The G7T (SPST-NO, SPST-NC, and SPDT types) and the G3TA I/O Relays can be mounted on the P7TF-05 Socket.
The P7TF-05 can be used for applications involving sequences that require slim relays, or to enable use of SPDT relays with the I/O Relay Terminal. To use part of the I/O Relay Terminal with SPDT specifications, insert an Output Short-Circuit Module into the I/O Relay Terminal, and use the P7TF-05 Socket in combination with an SPDT Relay for the Module’s output.
