Description
Product Introduction
The GE Fanuc IC693CPU350 is a single-slot modular CPU module engineered for Series 90-30 PLC systems. Unlike entry-level embedded baseplates, the CPU350 plugs directly into Slot 1 of a modular CPU baseplate (such as the 10-slot IC693CHS392 or 5-slot IC693CHS393), providing plant engineers with flexible, scalable processing power.
Powered by a 32 MHz 80386EX microprocessor, the IC693CPU350 delivers 32 Kbytes of configurable user memory for logic, register data, and hardware configuration tables. It handles up to 2,048 discrete I/O points and features built-in serial ports supporting SNP and SNP-X protocols, making it a reliable workhorse for mid-tier industrial automation loops.

Application Scenarios & The “Trench” Experience
At 2:20 AM during a heavy batch run at a beverage bottling plant, the main rinser and capper turret stopped mid-rotation. The watchdog LED on the installed IC693CPU350 flickered and went out—a high-voltage transient on the 24V bus had shorted the internal memory controller on the CPU card. With three transport trucks idling outside and hundreds of cases waiting to be palletized, the plant floor was burning thousands of dollars every hour the line remained still.
Application Scenarios
- Beverage Bottling & Packaging Lines: Manages high-speed bottle indexing, filler timing, capping turrets, and rejection gate solenoids.
- Municipal Water Treatment: Executes closed-loop PID control for chemical dosing, filter backwashing cycles, and multi-pump sequencing.
- Automotive Stamping & Weld Cells: Coordinates safety interlocking logic, robot handshakes, and hydraulic press stroke sequences.
- Material Handling & Warehousing: Controls high-speed tray sorters, automated storage and retrieval systems (ASRS), and shuttle cars.
Field Case Study
A chemical processing facility in Texas experienced an unrecoverable CPU crash on their solvent distillation skid. The legacy CPU350 module suffered flash memory corruption during a lightning storm, preventing the processor from completing its boot sequence and locking out all remote I/O loops. We pulled a fully tested, pre-cleared surplus IC693CPU350 module from our warehouse stock and dispatched it via priority courier. The site technician powered down the rack, swapped the card into Slot 1, uploaded the saved program via Proficy Machine Edition, and restored complete distillation monitoring before the night shift ended—saving an estimated $75,000 in ruined chemical stock.

Transparency SOP: Quality Assurance & Testing
Every IC693CPU350 module undergoes full physical and functional verification on live GE hardware before earning a spot in our ready-to-ship inventory.
- Inbound Visual Verification: Inspection for cracked plastic housing, bent backplane connector pins, damaged front serial port latches, and OEM revision label integrity.
- Modular Rack Power-On Test: Slotted into Slot 1 of an active GE IC693CHS392 modular baseplate driven by an IC693PWR330 power supply to verify OK, RUN, and SNP LED diagnostic cycles.
- Logic Download & Stress Test: Connected to Proficy Machine Edition via an RS-485 converter; downloaded a 32 KB benchmark program to test logic execution, register clearing, and continuous loop scanning for 4 hours inside a thermal chamber.
- Expansion Bus Handshake Sweep: Tested with attached local expansion baseplates (IC693CHS391) populated with digital and analog I/O modules to confirm 100% backplane data transfer stability.
- ESD Sealing & Final QC: Memory wiped back to factory default, real-time clock reset, and the module sealed in heavy-duty ESD shielding with custom-molded protective foam inserts.
The Veteran’s Tech Trap Guide
- ⚠️ Slot 1 Installation Only: The IC693CPU350 must be installed in Slot 1 of a modular CPU baseplate (IC693CHS392 or CHS393). It will not operate in an option slot, nor can it be installed on embedded CPU baseplates (like the IC693CHS397). Trying to force it into the wrong chassis will prevent system power-up.
- ❗ Never Hot-Swap the CPU Module: The GE Series 90-30 backplane does not support hot-swapping! Pulling or inserting the while the rack power supply is energized can arc the backplane connector pins, corrupt user memory, or destroy the CPU’s internal 3.3V/5V logic transceivers. Always kill rack power first.
- ⚠️ Back Up Your Program Before Swapping: Memory retention on this card relies on the lithium battery connected to the power supply module (IC693PWR321/PWR330). If you pull a dead CPU card out without having a saved backup file on your PC, you will lose the logic program completely once disconnected from battery power!
- ❗ Verify Firmware Compatibility: If you are replacing an older revision CPU350 with a newer one, verify that your software project in Proficy Machine Edition or VersaPro targets the correct firmware revision. A mismatch can cause communication warnings or hardware configuration rejection upon logic download.
Frequently Asked Questions (FAQ for Conversion)
Q: Is the GE Fanuc hot-swappable?
A: No. You must shut down main power to the Series 90-30 rack before removing or installing the module. Swapping it while energized will damage the CPU and backplane.
Q: What is the main difference between the and the IC693CPU360?
A: The features a 32 MHz 80386EX processor with 32 KB of user memory, whereas the IC693CPU360 offers higher processing speed and expanded memory capacity (240 KB) for larger logic applications.
Q: Can I plug the into an IC693CHS397 baseplate?
A: No. The IC693CHS397 baseplate already has an embedded CPU built directly into its circuit board. The requires a modular CPU baseplate, such as the 10-slot IC693CHS392 or 5-slot IC693CHS393.
Q: How do I load a program onto the ?
A: Logic and hardware configurations are loaded using Emerson/GE Proficy Machine Edition, VersaPro, or Logicmaster 90-30 software via a serial programming cable connected to the 15-pin D-sub port on the Series 90-30 power supply module.
Q: What warranty coverage comes with this surplus CPU module?
A: Every module includes a full 12-month replacement warranty. All inventory consists of genuine OEM units sourced from verified plant spares, fully cleaned, bench-tested, and certified on active Series 90-30 racks before shipment.
