Product Function Description
IC693CHS391 is the 10‑slot CPU main baseplate for GE Fanuc Series 90‑30 PLC platform, it is the mechanical and bus foundation of the whole PLC system。
This baseplate provides mechanical mounting positions for power‑supply module, CPU module, digital‑analog I/O modules and various option communication modules. The internal high‑speed parallel backplane bus realizes high‑speed data exchange between CPU and each plug‑in module, and distributes 5VDC backplane power to each module.
It is equipped with a dedicated 25‑pin expansion port on the right side. Users can connect additional expansion baseplates via expansion cables to expand more I/O slots, realizing multi‑rack distributed PLC architecture. The baseplate itself has no logic function, all control logic is completed by the CPU module inserted on slot1.
All IC693 series plug‑in modules can be directly inserted into this baseplate. It is widely used for maintenance and spare‑part replacement of legacy GE Fanuc automation equipment. Please pay attention to the total 5VDC current consumption of all modules, cannot exceed the power‑supply module output capacity.
Product Details
Industrial‑grade reinforced insulation backplane structure, metal mounting bracket, stable and durable, adapts to complex workshop electromagnetic‑interference environment. This legacy baseplate has been discontinued by original manufacturer, mainly used for old‑equipment overhaul and spare‑part replacement. Please confirm module total power consumption, expansion cable connection and rack number setting before commissioning. Strict ESD protection shall be adopted during installation.
