Description

The GE IC695CPE400 is a high-performance central processing unit (CPU) module designed for the PACSystems RX3i programmable automation controller platform, originally developed by GE Fanuc Intelligent Platforms (now part of Emerson). As one of the most advanced CPUs in the RX3i family, the GE IC695CPE400 delivers exceptional processing speed, large memory capacity, and robust communication capabilities to manage complex control strategies—including discrete logic, analog regulation, motion coordination, and data handling—all within a single deterministic scan cycle. Its dual-core architecture enables efficient multitasking, making it ideal for applications demanding high I/O counts, fast response times, and integration with enterprise-level systems.

Engineered for mission-critical industrial environments, the GE IC695CPE400 features an integrated 10/100/1000 Mbps Ethernet port for programming, HMI connectivity, and peer-to-peer messaging via protocols such as SRTP (Service Request Transport Protocol) and Modbus TCP. It also includes a serial port (RS-232/485) for legacy device interfacing or modem communication. With 128 MB of user memory and support for up to 32,000 I/O points, the GE IC695CPE400 scales seamlessly from mid-sized machine control to large distributed process systems. Its fanless design and conformal coating ensure reliable operation in dusty, humid, or thermally challenging settings—common in power generation, water/wastewater, and heavy manufacturing.

Technical Specifications

Main Features and Advantages

High-speed dual-core processing for complex automation tasks: The GE IC695CPE400 leverages a 1 GHz dual-core architecture to execute logic scans in under 1 millisecond—even with thousands of I/O points and multiple PID loops active. This performance enables real-time control of synchronized motion axes, high-speed packaging lines, or turbine protection systems where timing precision is critical.

Seamless integration with Proficy software ecosystem: Fully compatible with Proficy Machine Edition (PME) development environment, the GE IC695CPE400 supports IEC 61131-3 languages alongside ANSI C/C++, allowing engineers to implement custom algorithms (e.g., predictive maintenance models or adaptive tuning) directly on the controller. Online change capability permits logic updates without stopping the process—minimizing downtime.

Robust built-in communications for modern industrial networks: The integrated Gigabit Ethernet port on the GE IC695CPE400 supports multiple concurrent connections for programming, HMI data exchange (via GE’s Cimplicity or third-party SCADA), and peer-to-peer messaging with other PACSystems or Modbus TCP devices. This eliminates the need for separate communication modules in many applications, reducing cost and panel space.

Redundancy-ready for continuous operation: When paired with the IC695CRU320 redundancy module, the GE IC695CPE400 forms a hot-standby redundant CPU pair that automatically fails over in<100>

Fanless, ruggedized design for harsh environments: Unlike PC-based controllers, the GE IC695CPE400 uses solid-state cooling and conformal-coated circuitry to withstand vibration, condensation, and airborne contaminants. This reliability has made it a staple in oil & gas offshore platforms, mining conveyors, and municipal infrastructure worldwide.

Application Field

The GE IC695CPE400 is widely deployed across industries requiring high reliability and advanced control functionality. In water and wastewater treatment plants, it manages multi-stage filtration, chemical dosing, and pump sequencing across distributed lift stations, often interfacing with SCADA via its Ethernet port while maintaining local autonomy during network outages. In power generation, the GE IC695CPE400 controls auxiliary systems such as boiler feedwater, condenser vacuum, and turbine lube oil—executing safety interlocks faster than human reaction time.

Within manufacturing, the GE IC695CPE400 coordinates robotic cells, assembly lines, and material handling systems, leveraging its fast scan time to synchronize vision inspection with reject mechanisms at line speeds exceeding 200 parts per minute. In the oil & gas sector, it serves as the logic engine for compressor station control, integrating pressure sensors, motor starters, and emergency shutdown (ESD) valves into a single safety-certified platform. Because the GE IC695CPE400 supports both discrete and process control paradigms—and integrates easily with legacy Modbus RTU devices via its serial port—it remains a strategic choice for brownfield modernization projects aiming to extend the life of existing infrastructure while adding IIoT readiness.
