• Construction: Rugged black flame-retardant plastic housing (UL 94 V-0), gold-plated backplane connectors for reliability

Key Features

1. 5-Slot Expansion Capacity: Adds five I/O positions to scale system I/O count without replacing the main CPU rack.
2. Dedicated Power Supply Slot: Accommodates standard Series 90-30 power supplies to deliver regulated +5VDC logic and +24VDC I/O power to the backplane.
3. 25-Pin Expansion Port: Enables daisy-chaining of multiple expansion baseplates for distributed I/O architectures.
4. Rack Number DIP Switch: Allows unique addressing (0–7) for each expansion rack, critical for multi-rack system organization.
5. Passive Backplane Design: No onboard electronics; relies on the main CPU for control, reducing failure points and simplifying maintenance.
6. Hot-Swap Compatible: Supports insertion/removal of I/O modules during system operation (when used with hot-swap capable power supplies).
7. Industrial-Grade Durability: IP20-rated housing withstands vibration, temperature swings, and electrical noise in factory environments.
8. Seamless System Integration: Fully compatible with all Series 90-30 CPUs, I/O modules, and programming software; no special configuration required.
9. Wiring Simplification: Remote I/O placement reduces long cable runs from the main panel to field devices, minimizing noise and installation cost.
10. Cost-Effective Scalability: Enables incremental system expansion by adding individual racks instead of a full system redesign.

Applications

• Factory Automation: Expanding I/O for automotive assembly lines, packaging machinery, and material handling systems with distributed field devices.
• Process Control: Remote I/O racks for water treatment plants, food & beverage processing, and chemical facilities monitoring pumps, valves, and sensors.
• Building Automation: Scaling I/O for large HVAC systems, lighting control, and security systems in commercial buildings.
• Legacy System Upgrades: Adding I/O capacity to existing Series 90-30 installations without replacing the main CPU or control panel.
• Distributed I/O Architectures: Deploying remote racks near field devices to reduce wiring complexity in large facilities or multi-story buildings.
