Information

Overview Manuals Common Applications Product Precautions

General Electric IC693CHS391 is a ten-slot Series 90-30 modular CPU baseplate for a compatible CPU, power supply and local I/O or option modules.

Ten-slot Series 90-30 backplane for a modular CPU and compatible modules.
Dedicated power-supply position at the left side of the baseplate.
Slot-specific hardware sequence retained by the controller project.
Panel-mounted rack requiring documented bonding and cabinet clearance.

The baseplate remains matched to its documented cabinet position, power supply, CPU and module sequence. Commissioning restores the saved hardware configuration and verifies rack diagnostics and every affected I/O function.

Important Notice: Confirm IC693CHS391, every installed module, cable, keying point and protective-earth connection before release.
