I/O Block G7TC Single Cable Connection to PLC Means Space is Saved and Less Control Panel Wiring is Required. Compact size: 182 (W) 85 (D) 68 (H) mm (8-point Output Block width is 102 mm). Connects to the PC through the connecting cable (G79 Series) and connector, and requires only a snap-in operation. Surge suppressor circuit built-in. Immediate recognition of I/O signal status using LED operation indicators. G3TA I/O Solid-state relay can be mounted instead of G7T. Mounts easily on a DIN track. Approved by UL, CSA (except for G7TC-OC16-1). Ordering Information Model Number Legend A G7TC I/O Block is a combination of (8 or 16) G7T I/O Relays with SPST-NO specifications and a P7TF I/O Terminal. G7TC- - 12 3 4 1.

The rated current and coil resistance are measured at a coil temperature of +23C 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 +23C. 3. The value for maximum voltage is the maximum value within the allowable voltage fluctuation range for the relay coils 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.
