IC693CHS397 | GE Fanuc Series 90-30 5-Slot Programmable Controller CPU Baseplate

Module Description

The IC693CHS397 serves as the primary foundation for a GE Fanuc Series 90-30 PLC system. As a 5-slot CPU baseplate, it is designed to house the Power Supply module, the CPU (or a specialty Motion Mate module), and up to four additional I/O or option modules. This baseplate is designated as "Rack 0" in a hardware configuration and provides the essential communication bus and power distribution interface between the processor and the field signals. Unlike expansion bases, the IC693CHS397 features the specialized Slot 1 dedicated specifically to the CPU module.

Technical Specifications

Engineers should note that while the physical footprint is compact, the IC693CHS397 maintains full compatibility with the high-speed Series 90-30 backplane bus.

Hardware Installation and System Expansion

The IC693CHS397 is equipped with a 25-pin D-shell expansion port on its right side. This allows the local CPU to communicate with expansion or remote baseplates. When calculating system power requirements, the 270 mA draw of the baseplate itself must be added to the total consumption of the installed modules to ensure the Power Supply (typically IC693PWR321 or IC693PWR330) is not overloaded.

Baseplate Comparison: IC693CHS397 vs. IC693CHS391

Choosing the correct baseplate depends on the required I/O density and cabinet space:

• IC693CHS397: 5-slot version, ideal for small-scale applications or distributed control where panel space is at a premium.

• IC693CHS391: 10-slot version, utilized for centralized control systems requiring a high volume of I/O modules in a single rack.

Engineering FAQ

Can I install an I/O module in Slot 1 of the IC693CHS397?

No. Slot 1 is unique on a CPU baseplate and is wired specifically for the processor. I/O modules must be placed in Slots 2, 3, 4, or 5.

Does this baseplate support Remote I/O?

Yes. By using the integrated 25-pin expansion port, this CPU baseplate can connect to additional IC693 expansion or remote racks, extending the total I/O capacity beyond the local 5 slots.

What power supply modules are compatible with this rack?

The IC693CHS397 is compatible with all Series 90-30 power supplies, including 120/240VAC, 24VDC, and 125VDC variants.
