GE IC695CPU320-HY

Product Overview

The GE IC695CPU320-HY is a Central Processing Unit for the GE Fanuc PACSystems RX3i platform. It serves as the main processor in an RX3i PLC system, executing application logic, managing data, and coordinating communication between the controller and connected I/O or automation devices.

The IC695CPU320-HY is a specific revision of the IC695CPU320 CPU family. GE documentation identifies the -HY version as an applicable CPU320 revision.

With its combination of high-speed processing, onboard memory, and serial communication, the CPU320 is suitable for machine control and industrial process applications where reliable PLC processing is required.

Processing and Communication

The IC695CPU320-HY is designed to provide the central processing capability of an RX3i control system. Its 1 GHz Celeron M processor allows the controller to execute PLC programs and process automation data at high speed.

Two built-in serial communication ports provide connection options for programming devices, HMIs, supervisory systems, and other serial equipment. The supported interfaces include RS-232 and RS-485, with protocols such as SNP, Serial I/O, and Modbus RTU Slave available within the CPU320 platform.

The controller also supports communication through the RX3i backplane, allowing it to exchange data with compatible I/O and option modules installed within the automation rack.

RX3i System Integration

A major advantage of the CPU320 platform is its ability to work within a flexible RX3i architecture. The controller can be installed in compatible RX3i universal backplanes, including 12-slot and 16-slot configurations used with the platform.

The CPU also supports many Series 90-30 I/O modules, making the RX3i platform useful for modernization projects in which existing field I/O is retained while the controller is upgraded.

This migration capability can reduce the need for a complete replacement of an established automation system. Existing programs and field wiring can potentially be retained where the hardware and application configuration are compatible.

Typical Applications

The GE IC695CPU320-HY can be used in a broad range of industrial automation environments, including:

• Manufacturing and production machinery
• Process control systems
• Packaging and material handling
• Factory automation
• Machine monitoring and control
• Industrial HMI and SCADA integration
• Series 90-30 modernization projects
• Legacy PACSystems RX3i maintenance

Its processing capacity and communication functions make it suitable for control systems that require centralized PLC logic execution together with connections to local and legacy automation equipment.

Installation and Maintenance

Before installing an IC695CPU320-HY, verify the complete catalog number and revision against the existing controller. Firmware compatibility, application program requirements, backplane configuration, communication settings, and connected I/O should all be checked before replacement.

The CPU320 family operates within a 0 to 60°C temperature range. Proper cabinet ventilation and suitable environmental conditions should therefore be maintained during operation.

During servicing, technicians should use appropriate ESD protection and follow the manufacturer’s approved shutdown procedures. The condition of the battery-backed memory system, serial connectors, backplane contacts, and status LEDs should also be checked as part of routine maintenance.

For replacement applications, confirming the IC695CPU320-HY revision is especially important because the CPU320 family has been produced in multiple revisions. Correct model identification helps reduce compatibility issues and supports a smoother replacement process.
