Executes the Series 90-30 control program and coordinates rack I/O.
Technical Summary
IC693CPU350-EJ is a CPU350 module for the legacy Series 90-30 PLC platform. It executes the application program and coordinates the configured I/O and communications resources of the controller.
EJ is part of the complete module release identity. A replacement decision must include the rack and power arrangement, programming-software compatibility, firmware level, memory contents and any serial or communications dependencies.

Features
Stores controller configuration that must be protected before hardware replacement.
Uses an explicit EJ release label for traceable service selection.
Supports legacy-system maintenance when firmware, software and communications are reviewed together.
Compatibility
- Confirm the IC693CPU350-EJ label, CPU baseplate, power supply and complete rack layout.
- Record firmware information and the programming software used to maintain the project.
- Inventory communications modules, option modules, serial devices and external memory or backup hardware.
- Use Emerson migration documentation if moving to a different CPU family or current controller platform.
Replacement
- Create and validate a full project backup before removing the CPU.
- Record switch positions, battery state, firmware, fault table and communications configuration.
- Apply the approved machine shutdown and lockout procedure before module removal.
- Install the verified CPU, restore the project and compare the resulting hardware configuration.
- Test I/O, communications, retentive data, sequence recovery and all safety-related interfaces.
FAQ
Can a CPU350 with another suffix replace IC693CPU350-EJ?
Only after firmware, hardware revision, project compatibility and the Emerson service path are confirmed; the suffix should not be ignored.
What backup is required before changing IC693CPU350-EJ?
Keep the complete project, hardware configuration, reference tables, communications settings, retentive-data plan and current fault information.
What rack information should be supplied for IC693CPU350-EJ?
Provide the CPU baseplate and power-supply labels, every module and slot, expansion arrangement and any communications adapter.
How should battery and retained data be handled for IC693CPU350-EJ?
Follow the Series 90-30 maintenance procedure, document battery condition and preserve required retained values before power is removed.
What proves a replacement IC693CPU350-EJ is ready for production?
A configuration comparison plus controlled tests of I/O, networks, sequence restart, retentive data and machine interlocks is required.
