The IC697MEM733 memory module is a 256 KB CMOS extended memory module manufactured by GE Fanuc. The IC697MEM733 memory module is classified as the 90-70 series and is used to provide logic and data memory. It is typically used in GE 789, 788, 782, 781, and 780 CPU modules, installed as a daughter board and placed in the same slot as the CPU module being served. The IC697MEM733 memory module does not require any additional installation slots. The memory expansion module can be configured for data or program storage. The IC697MEM733 memory module is also equipped with a lithium battery, usually placed on the substrate housing. Lithium batteries are important in ensuring memory retention, especially in the event of a power outage.
In case of power failure, the lithium battery can ensure that the user memory in the IC697MEM733 module remains intact. In addition, the lithium battery is responsible for ensuring that the calendar clock is retained and that there is no need to reset the date and time on the PLC when the CPU has to be restarted. If kept at 10 degrees Celsius or 20 degrees Fahrenheit, the battery life of the IC697MEM733 memory module is about 68 years. The memory can then be retained without power for up to six months. The flash memory in the module is retained in case of power failure with or without a battery. Before removing the battery for replacement, it is crucial to install a new battery before removing the existing one to avoid any memory loss.
