The GE Fanuc IC670CHS002 terminal block is an I/O terminal block that is equipped with box terminals, and designed and manufactured by GE Fanuc to serve as the mounting base for 2 independent I/O modules and for providing them with the platform they need for communication connections, power supply connections, and terminals for user connections. Any type of GE Fanuc compatible modules can be attached or detached from the GE Fanuc IC670CHS002 I/O terminal block without the need to disconnect the system from the power source. This means that the terminal block is hot-swap compatible. The added modules can be firmly screwed into the terminal block (the maximum terminal torque is 4.5 pounds on an inch) to avoid accidental disconnection due to the excessive vibrations that often occur in industrial applications.

Modules that are compatible with the GE Fanuc IC670CHS002 I/O terminal block with box terminals can easily be mounted just by pressing them onto the terminal block. The users must pay attention to the alignment slot provided from the factory on this terminal box. If the additional module does not have a projecting tab that clicks into that slot, it means the module is not compatible and will not fit tightly. Two or more GE Fanuc IC670CHS002 I/O terminal blocks can be connected in a daisy-chain formation, while always respecting the data flow order in the network. One terminal block connection cable is supplied with each I/O terminal block, and a longer, 21-inch version is available separately. The users can determine which type of module should be installed in each connection slot by using a lettered key system that will allow the connection of only 1 type of module per slot.
