4. Product Introduction & Supply Chain Strategy
The GE IC693CPU350-BC is a central processing unit module for the Series 90-30 PLC system. It executes user logic, manages I/O, and provides communication capabilities for industrial automation and process control applications.
New Surplus acquisition supports efficient inventory management for installed 90-30 bases. It avoids refurbished risks such as degraded performance or unexpected failures while enabling last-time-buy and cross-site sharing strategies. This keeps total cost of ownership low and minimizes downtime in mature but still-critical control systems.
5. Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety) Lock-out/tag-out PLC power. Use ESD protection and document current CPU settings, program backup, and hardware configuration. Photograph module placement.
Stage 2: Removal Power down the rack. Release the CPU module from its slot and remove it carefully.
Stage 3: Installation (Clone & Seat) Insert the new IC693CPU350-BC into the CPU slot until fully seated. Ensure proper alignment with the backplane.
Stage 4: Power-On & Testing Restore power. Load or restore the application program via programming software. Verify I/O communication, scan times, and system diagnostics before resuming operations.

6. Firmware/Software Versions & Upgrade Notes
The IC693CPU350-BC runs firmware specific to the CPU model. Use Logicmaster or Proficy Machine Edition for programming and firmware updates.
Match firmware versions when replacing to maintain compatibility with existing logic and I/O modules. Upgrades should be tested offline first to prevent logic or communication issues during the swap.
7. Frequently Asked Questions (FAQ)
Yes. This is original GE stock, never installed, and fully tested to OEM specifications.
Q: Why choose New Surplus for Series 90-30 CPUs? Legacy PLC processors must deliver consistent performance. Refurbished units risk memory or processing faults that lead to production interruptions.
Q: Is the Series 90-30 obsolete? The platform is mature with limited new production. Strategic spares help sustain operations cost-effectively.
Q: What software programs this CPU? Logicmaster 90 or Proficy Machine Edition (CIMPLICITY ME).
Q: What warranty applies? We provide a 1 year warranty on this New Surplus CPU module for defects and operational reliability.
Q: Does it include Ethernet? The BC revision typically supports Ethernet communications for network integration.
Q: Can it replace earlier CPU versions? Yes, with appropriate configuration and program compatibility checks. Consult the migration guide for best results.
