Technical Specifications

Note: Electrical parameters such as memory capacity, scan time, and I/O point counts vary by firmware revision. DriveKNMS does not publish unverified specifications. Contact us for confirmed unit-specific data prior to purchase.

Solving the Discontinued Hardware Crisis

The GE Series 90-30 platform was deployed extensively across process industries — oil & gas, water treatment, automotive assembly, and food manufacturing — throughout the 1990s and 2000s. Many of these installations remain operational today, embedded within larger DCS or SCADA architectures where the cost of replacement is not simply the hardware, but the entire surrounding system logic.

Facilities that have maintained a strategic spare of the IC693CPU372 have consistently avoided this crisis. A single unit held in climate-controlled storage represents an insurance policy against a failure event that could otherwise halt production for weeks.

How to extend your GE Series 90-30 asset life by 5 to 10 years — without a full system overhaul:

Condition & Reliability Assurance

Discontinued hardware sourced from the secondary market carries inherent risk. DriveKNMS applies a structured 5-step qualification process to every IC693CPU372 unit before it is offered for sale:

1. Visual and mechanical inspection: Full external examination for physical damage, pin deformation, and housing integrity. Units with evidence of improper extraction or installation are rejected.
2. Electrolytic capacitor assessment: Series 90-30 CPU modules contain electrolytic capacitors that degrade over time, particularly in high-temperature environments. Each unit is assessed for capacitor bulging, leakage, and ESR deviation. Units with compromised capacitors are either reconditioned by qualified technicians or removed from inventory.
3. Firmware version verification: The firmware revision is read and documented. This information is provided to the buyer prior to shipment to ensure compatibility with the target system.
4. Pin and connector corrosion inspection: All edge connector pins are examined under magnification for oxidation and corrosion. Affected pins are treated with appropriate contact cleaner and re-inspected before approval.
5. Functional power-on test: Where test fixtures are available, units undergo a controlled power-on sequence to verify basic initialization and communication response.

Units that do not pass all five stages are not sold as functional spares. DriveKNMS does not sell untested or uninspected units as operational replacements.

Key Features for System Maintenance

• Drop-in replacement: The IC693CPU372 is a direct physical and functional replacement for failed units within the same Series 90-30 rack. No rack modification, no rewiring, no I/O reconfiguration.
• No reprogramming required: Restoring a previously backed-up program to a replacement CPU is a standard procedure. It does not require a controls engineer to rewrite or re-validate the application logic — provided a current backup exists.
• Avoids engineering reconstruction costs: Migrating a Series 90-30 system to a current-generation PLC platform requires full I/O remapping, HMI screen rebuilds, network reconfiguration, and FAT/SAT testing. This process typically requires 6–18 months of engineering time. A replacement CPU eliminates this cost entirely for facilities not yet ready to migrate.
• Maintains existing operator familiarity: Operators trained on Series 90-30 systems do not require retraining when a CPU is replaced in-kind. Retraining costs and the associated productivity loss during the learning curve are avoided.

How do I confirm the unit is genuine and not counterfeit?
All units sourced by DriveKNMS are inspected for authenticity markers including label consistency, PCB markings, and component date codes. We provide documentation of the unit's condition and firmware version. Buyers are encouraged to request this documentation before finalizing purchase.

Can you source specific firmware versions?
DriveKNMS documents firmware versions on all units in inventory. If your system requires a specific firmware revision for compatibility, contact us before purchase and we will confirm availability.
