Emerson PACSystems RX3i IC695CPE330 – High-performance CPU module for scalable machine and process control

The Emerson IC695CPE330 is a PACSystems RX3i CPU module designed for fast logic execution, deterministic control, and flexible Ethernet connectivity. From my experience, it’s a solid choice when you need to modernize an RX3i rack or expand a line without rewriting everything from scratch. You might notice that projects using Proficy Machine Edition typically drop in smoothly, and the embedded Ethernet makes commissioning and diagnostics much easier on busy lines.

Application Fields

The IC695CPE330 fits well in machine automation, packaging lines, metals processing, water and wastewater, oil and gas skids, power generation auxiliaries, and OEM equipment upgrades. One thing I appreciate is how it helps standardize on RX3i across mixed assets—older racks can often be kept, while you refresh the CPU and Ethernet layer.

• Packaging and material handling: quicker scan and Ethernet diagnostics for conveyors and sorters.
• Process skids: stable loops and alarms with straightforward SCADA connectivity.
• Utilities and infrastructure: typical redundancy at the network/HMI level without overcomplication.
• Brownfield modernization: keep I/O and wiring, swap in a modern CPU to reduce downtime.

Advantages & Value

• Reliability: Proven RX3i architecture that runs 24/7 in many plants; fewer nuisance stops.
• Compatibility: Works with existing RX3i racks and I/O modules, avoiding full system replacements.
• Lifecycle savings: Lower engineering effort by reusing logic, tags, and existing panel layouts.
• Connectivity: Ethernet services typically support HMIs, historians, and remote maintenance.
• Supportability: Clear firmware paths and common toolchain help your team maintain and scale.

Recommended Accessories and Supporting Components

• IC695PSA040 – RX3i power supply for 5 VDC backplane power.
• IC695CHS012 – 12‑slot RX3i rack (panel mount), ideal when expanding I/O count.
• IC695PNC001 – PROFINET Controller module if you plan to run distributed I/O over PROFINET.
• Industrial Ethernet switches (managed) – For segmentation, ring redundancy, and QoS in larger cells.

Installation & Maintenance

• Cabinet and rack: Mount in a PACSystems RX3i rack; keep at least 50 mm clearance for ventilation. Avoid direct heat sources.
• Power and grounding: Use a dedicated RX3i power supply; bond cabinet ground properly; segregate AC, DC, and signal wiring.
• Networking: Use industrial-rated Ethernet cables; consider VLANs or ring topologies when uptime is critical.
• Firmware management: Align CPU firmware with your Proficy Machine Edition version; back up projects before updates.
• Routine care: Periodically check connector tightness, clean dust with dry air, verify cabinet temperature and fan filters.
• Safety: De-energize the rack before inserting or removing modules; follow ESD precautions.

Quality & Certifications

• CE and UL/cUL compliant for industrial control equipment (typical for RX3i family).
• RoHS compliant hardware in many regions.
• Manufacturer warranty varies by region; our warranty: 365 days from shipment.

If you’re standardizing on PACSystems RX3i, the IC695CPE330 seems to be a practical CPU choice—enough performance headroom, straightforward Ethernet, and minimal disruption to existing panels.
