Serving as the primary foundation for system configuration, the GE Fanuc Emerson IC693CHS391 is a 10-slot modular CPU baseplate from the Series 90-30 family. It accommodates one (1) CPU slot, multiple non-CPU or I/O slots, a power supply interface, and an I/O expansion bus port to support flexible system design. The baseplate integrates a local electronic backplane that delivers power and communication signals to all installed modules for stable operation. Only one (1) CPU baseplate is permitted per system, while additional baseplates may function as expansion or remote I/O units. The IC693CHS391 may possibly be utilized across automation facilities in North America, Europe, Asia, and other worldwide environments employing GE Fanuc Series 90-30 architectures.
