The GE Fanuc IC697CHS791 rack is a standard 9-slot rack that is front-mounted. This 9-slot rack is part of the GE Series 90-70 product line. The purpose of the IC697CHS791 9-slot rack is to be part of the base of a programmable logic controller or PLC system and to host up to 9 PLC modules at a time. The IC697CHS791 rack’s dimensions are 11.15 x 19 x 7.5 inches. This rack is made to mount in the front on another rack that is a standard 19-inch or 480-millimeter rack, and it normally does not need to have a fan installed to cool it down. The IC697CHS791 rack can be used in any Series 90-70 PLC I/O and CPU configuration and they accept all types of GE Series 90-70 IC697 PLC modules.

On the GE IC697CHS791 9-slot standard rack, there is a power supply connector located to the left of all the module slots where the power supply module for the rack is connected. The power supply can be an AC supply or a DC supply. This rack can also be connected to another rack and they can share a power supply in an extended I/O application setup, and this connection is made possible with a GE power supply expansion cable kit. The IC697CHS791 9-slot rack needs 0.5 Amps of current from the I/O Bus. The modules that it hosts are secured in place with mechanical keying. Modules that have been keyed in place can be removed if necessary, but keying prevents them from being removed to easily, installed in the wrong slot, or from being used to replace the wrong module.
