Key Features
- Dual-Bus Architecture
- PCI Bus: Supports high-speed RX3i modules (motion control, high-speed counting, Ethernet).
- Serial Bus: Ensures backward compatibility with legacy Series 90-30 modules, protecting existing investments.
- Hot-Swap Capability
- Modules can be inserted/removed while the system is powered on, eliminating downtime for maintenance or upgrades.
- High Slot Density
- 12 slots accommodate CPUs, digital/analog I/O, communication cards, and specialty modules, ideal for medium-to-large automation systems.
- Robust Industrial Design
- Vibration and EMI resistance for harsh factory environments.
- Integrated grounding bar for noise reduction and system stability.
- Flexible Expansion
- Supports serial expansion connectors for remote backplanes and distributed I/O architectures.
Application Scenarios
- Manufacturing: Automotive assembly lines, packaging machinery, machine tools, robotics control systems.
- Process Industries: Chemical, petrochemical, oil/gas, water/wastewater treatment plants.
- Energy & Power: Power generation (gas/steam turbines), power distribution, renewable energy systems.
- Infrastructure: Building automation, smart equipment control, transportation systems.
- Legacy System Migration: Upgrading Series 90-30 PLCs to RX3i while reusing existing I/O modules。
Additional Notes
- Replacement: Directly replaced by IC695CHS016 (16-slot backplane) for larger system expansions.
- Installation: Must be mounted horizontally in an IP20+ enclosure; adhere to cooling clearance requirements to prevent overheating.
- Warranty: Typically 12 months for new/refurbished units (varies by supplier).
