About the IC670CHS102

The GE Fanuc Field Control IC670CHS102 Input/Output Chassis Terminal Block is used as a terminal block interface to connect GE Fanuch input/output modules to field device wiring without having to physically connect these modules directly. Using this type of terminal block in lieu of direct module connections helps keep the panel organised, avoids confusing wiring configurations, and simplifies troubleshooting by allowing modules to be inserted and removed (even if power has not been turned off).The GE Fanuc IC670CHS102 Input/Output Chassis Terminal Block has three separate groups of terminal connection points that share a common connection, but are isolated from each other. These groups are referred to as Groups A, B, and E. Groups A and B are used for power connections, while Group E is used as a common reference point for application wiring.

GE Fanuc input/output modules can be plugged in or removed from the GE Fanuc IC670CHS102 Input/Output Chassis Terminal Block without prior disconnection of power. However, this operation (known as hot plugging) should not be performed in hazardous locations as it may generate sparks that could start a fire in those locations. The hot-swap operation is available only if the Bus Interface Unit or BIU in the system is version 2.1 or later. Each GE Fanuc IC670CHS102 input/output chassis junction box can accommodate up to two individual modules with catalogue number suffix ‘J’ or larger. There are 37 screw connection points in the junction box, each capable of connecting 1 AWG#14 wire or 2 AWG#18 to AWG#22 wires.

The I/O terminal blocks are universal wiring bases that provide module mounting, backplane communications, and user connection terminals. Two modules can be mounted on one terminal block. Modules are screwed to the terminal block for vibration dcs-sis.com resistance. Removal of the modules does not interfere with field wiring.

Each I/O module has three groups of isolated common terminals: Group A (internally connected together) and Group B (internally connected together) are typically used for power connections. group E has five common terminals that are internally connected together and are isolated from the power and point terminals. They can be used for application wiring as required. Terminals 1 – 16 are used for I/O wiring.
