The GE Fanuc Field Control IC670CHS001 I/O base is a type of terminal block that can have modules modules on top of it, enabling communications between modules connected into its backplane and serving as endpoint terminals for connections to external field devices. They support the installation of 2 modules. These modules are mechanically screwed to the GE Fanuc IC670CHS001 I/O base in order to avoid accidental disconnections due to equipment vibration. The I/O base terminal block comes from the factory with protective barriers that prevent contact with adjacent cables and short circuits during the connection or disconnection of devices. An important thing to take note of is that these modules support the connection and disconnection of cabling even while the module is powered on.

There are 37 screw terminals in a GE Fanuc IC670CHS001 I/O base. Two of those terminals, marked as terminals A and B, are for power supply connections and the remaining 35 are used for individual terminal connections. The terminals can accommodate AWG #14 (2.1 square millimeters) through AWG #22 (0.35 square millimeters) cables. The GE Fanuc IC670CHS001 I/O base is keyed in order to avoid the incorrect connections of additional I/O modules. These additional modules are mounted onto the base by pressing them firmly against it once they have been placed in the right positions. It is always necessary to tighten the screws of the module into the base, in order to prevent vibrations from disconnecting the modules from the I/O base. The manufacturer recommends using a maximum torque of 8 to 10 pounds on an inch.
