Features:
- Ten numbered module positions in a modular CPU baseplate
- Dedicated power-supply location at the left side
- Backplane distributes power and CPU communications to installed modules
IC693CHS391 forms the central rack of a Series 90-30 system that needs more local positions than the five-slot alternative.
The mechanical frame, connectors, and backplane establish a common installation plane for controller and I/O hardware.
Slot order is part of the PLC configuration, so physical replacement work must reproduce the intended layout.
The General Electric IC693CHS391 Series 90-30 10-slot CPU baseplate may remain available for quotation and installed-system support from Apter Power.

Baseplate relationships
- CPU location: A modular Series 90-30 CPU is installed in a numbered slot of this CPU baseplate.
- Local capacity: Ten positions are available for processor, I/O, and supported option modules.
- Backplane path: System power and module-to-CPU communication travel through the rack backplane.
- Expansion support: The CPU baseplate can connect to configured expansion or remote baseplates.
Physical organization
- Power position: The Series 90-30 power supply mounts at the extreme left.
- Numbered slots: Module positions are identified in sequence for configuration and maintenance.
- Module keys: Only mechanically and electrically compatible Series 90-30 modules belong in the rack.
- Layout record: Existing slot assignments should be applicable before moving modules to a replacement baseplate.
Panel mounting and service
- Support surface: The baseplate is secured to a rigid panel surface before modules are inserted.
- Connector care: Backplane connectors must remain clean and undamaged during module exchange.
- Power isolation: Baseplate power is removed before installing or removing modules.
- Cable clearance: Panel layout leaves room for front wiring, expansion connectors, and module retention hardware.
Supported rack uses
- Large local stations: Ten slots accommodate PLC nodes with numerous local discrete and analog modules.
- Mixed control racks: Processor, communication, and specialty modules can share the central baseplate with I/O.
- Expansion masters: IC693CHS391 can serve as the CPU rack at the head of a multi-baseplate installation.
- Control retrofits: The baseplate supports reconstruction of established Series 90-30 panels that use ten local positions.
