Technical Specifications Total Slot Quantity: 12 slots for RX3i series modules Compatible Module Types: RX3i CPU, power supply, I/O modules and accessory modules Backplane Bus Rate: RX3i high‑speed parallel backplane bus Mechanical Installation: Cabinet wall‑mount installation Operating Temperature: ‑40 ℃ to +70 ℃ Storage Temperature: ‑50 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard RX3i 12‑slot rack form factor Certifications: CE, UL industrial control compliance
Functional Features Provides 12 mounting slots for assembling diverse RX3i series modules. Realizes high‑speed data communication between each module through internal backplane bus. Supports hot‑swap operation of individual modules without powering off the whole rack. Delivers stable power distribution path from power supply module to each slot position. Precise mechanical positioning ensures reliable golden‑finger contact for inserted modules. Allows flexible configuration of CPU, power supply, input and output modules according to project demands.
Application Scenarios Main hardware framework for RX3i automation control cabinet. Process control system for chemical, petrochemical and power industries. Automation control equipment for manufacturing and production lines. Metallurgy industry logic control and interlock system hardware carrier. Water‑treatment and municipal industrial automation control projects.
Structural Characteristics Integrated metal frame structure for cabinet installation. Internal printed circuit backplane with golden‑finger connectors for each slot. Standard positioning guide rails for smooth module insertion and extraction. Locking matching structure cooperating with module locking mechanism. Grounding terminals for rack protective earthing connection. Anti‑corrosive surface treatment adapting to industrial cabinet environment.
Working Principle Each inserted module is mechanically fixed on the rack and electrically connected to internal backplane golden‑finger connectors. The power supply module distributes operating power to every slot via backplane copper traces.
Installation Requirements Securely fasten the rack on cabinet mounting plate with standard mounting screws. Complete reliable protective grounding connection for rack grounding terminal following official grounding specification.
