PRODUCT INFORMATION
Product Overview
The General Electric IC697MEM733 is an expansion memory module for the Series 90-70 control family. It provides a 256 KB capacity using volatile CMOS technology. The module mounts directly onto the host CPU module. It draws operating power through the backplane connection. This unit processes control instructions using a 32-bit architecture.
The module integrates lithium battery backup capabilities for stored data protection. A connected lithium battery provides memory retention for up to six months without system power. This prevents program loss during extended outages and controlled shutdowns. The unit serves as a functional spare part or expansion accessory for legacy automation controllers. Its net weight is 1.19 lbs or 0.54 kg.
