Description
Product Description
The IC697CHS782 is a VME-based rack chassis engineered for the GE Fanuc Series 90-70 PLC platform. It serves as a hybrid integration backplane, enabling the installation of both IC697 control modules and industry-standard VMEbus cards within the same system. This makes it suitable for applications where PLC control must coexist with high-performance computing or third-party interface modules.
Its 17-slot architecture, combined with a VME-compliant backplane, provides flexibility for system expansion while maintaining deterministic communication across modules. The chassis is designed for enclosure mounting and supports both standard convection cooling and optional forced-air configurations for higher power densities.

FAQ
Q: Can this rack be used with non-GE modules?
A: Yes, it supports standard VMEbus modules in addition to GE IC697 PLC modules.
Q: Is a power supply included with the rack?
A: No, a compatible IC697 series power supply must be installed separately.
Q: Does the rack support high-power configurations?
A: Yes, but an optional fan assembly is recommended when using high-power modules.
Q: Can multiple racks be connected in one system?
A: Yes, multi-rack configurations are supported using appropriate expansion cables.
