I/O Relay Terminal G7TC
Caution
Product Description
A terminal relay which uses a single cable to connect to all PLC I/O units, helping save on space and helping reduce the amount on panel wiring required.
[Features]
· Allows for batch wiring to SYSMAC with a single connector cable, reducing the amount of panel wiring steps and helping save on space.
· Compact size terminal for both input and output at 182 mm* (W) × 85 mm (D) × 68 (H) mm (*102 mm for 8 point type.)
· Single-action connection to SBC with a connector. Features a built-in coil surge absorbing element.
· Features operation indicating LEDs, making it quick and easy to check the ON/OFF status of the I/O signal.
· Model G3TA I/O solid state relays can also be mounted.
· Conforms to UL and CSA international standards (except Model G7TC-OC16-1).
[Applications]
· Equipment that connects to PLCs, DeviceNet, and CompoNet, helping save on man hours and space.
