Key Features
-
System I/O Expansion
- Adds 5 additional slots for standard Series 90-30 discrete/analog I/O modules, communication modules, and specialty options.
- Accommodates a dedicated power supply module to support extended I/O loads, ensuring stable power distribution across the rack.
-
Seamless Platform Compatibility
- Fully compatible with all Series 90-30 CPUs and I/O modules, enabling drop-in replacement and system upgrades without reconfiguration.
- Features a rack number selection DIP switch for easy addressing in multi-baseplate systems.
-
Rugged Industrial Design
- Heavy-duty, vibration-resistant construction for panel mounting in harsh factory environments.
- Common grounding requirement ensures electrical noise immunity and signal integrity across the expansion bus.
-
Flexible Distributed Layouts
- Supports remote I/O deployment via up to 15-meter expansion cables, ideal for large machines or production lines requiring distributed control.
- Daisy-chain capable: multiple IC693CHS398 baseplates can be connected to scale I/O capacity as needed.
