I/O Relay Terminal

G7TC

Single Cable Connection to PLC Means Space is Saved and Less Control Panel Wiring is Required.

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.
