Emerson IC695CPE330 RX3i Controller
A high-performance RX3i controller with 64 MB user memory, three Gigabit Ethernet ports and redundant remote-I/O capability.
Product Overview
IC695CPE330 is a backplane-mounted PACSystems RX3i controller for machine and process control. Emerson specifies 64 MB user memory, 32 Kbits of discrete I/O and 32 Kwords of analog I/O capacity.
The controller provides three 10/100/1000 Ethernet ports, including a two-port switched interface, and supports a broad industrial protocol set. It can manage 32 simplex or 20 redundant remote I/O devices directly, and as many as 255 simplex devices with PNC001.
Performance
- Three Gigabit Ethernet ports support controller, HMI, supervisory and remote-I/O networks.
- Protocols include SRTP, Modbus TCP/IP, OPC UA, EGD, PROFINET, DNP3, IEC 61850 client, IEC 104 server and HART pass-through.
- Non-transparent OPC UA server redundancy is supported under the documented architecture.
- A USB-A 2.0 interface and CFast memory-card position support service and storage workflows.
- An optional energy-pack arrangement supports orderly memory retention during power loss.

System Integration
- Back up the project, retained variables, certificates, users, network settings, firmware and CFast content.
- Record every IC695CPE330 Ethernet port, remote-I/O controller, energy pack and rack component.
- Verify PAC Machine Edition, PNC/PNS, remote-I/O and firmware compatibility before restore.
- Re-establish trust stores, OPC UA settings and network segmentation under the site cybersecurity procedure.
- Validate memory retention, all protocols, remote I/O, time synchronization, controller scan and machine interlocks.
Applications
- High-performance machine and process control on the RX3i platform.
- PROFINET remote I/O with simplex or redundant architecture.
- OPC UA, Modbus TCP, SRTP and EGD integration between OT systems.
- Modernization projects requiring multiple Gigabit Ethernet interfaces and large user memory.
FAQ
What must be captured before ordering an IC695CPE330 replacement?
Record the complete suffix, firmware, PAC Machine Edition release, rack and energy-pack details, all three port assignments, remote-I/O topology, certificates and enabled protocols.
How should IC695CPE330 cybersecurity data be protected during exchange?
Export the project and network settings, preserve certificates and trust relationships, document users and access controls, and restore them through the approved secure-deployment process.
Can IC695CPE330 be inserted into any RX3i rack without compatibility checks?
No. Check backplane, power, programming software, firmware, PNC/PNS modules, option modules and environmental approvals for the exact system.
What network test should follow an IC695CPE330 replacement?
Verify each physical port, redundancy or ring state, controller and HMI sessions, remote I/O, every enabled protocol, time synchronization and failover behavior.
When should the IC695CPE330 energy pack be included in a quotation?
Include it when the installed retention design uses the pack or when diagnostics, age or cable condition show that the companion hardware also needs renewal.
