Solving the Discontinued Hardware Crisis

The GE Series 90 Micro PLC platform was deployed extensively throughout the 1990s and 2000s across industries including food and beverage processing, water treatment, discrete manufacturing, and building automation. The IC670ALG330 analog output module sits at the interface between the PLC's digital logic and the physical process — driving control signals to valves, variable frequency drives, and other analog-actuated field devices. There is no modern drop-in equivalent that fits the IC670 backplane without hardware modification.

Facilities still operating on this platform face a structural problem: the system works, the operators know it, and the process it controls has been stable for years. The business case for a full control system upgrade is difficult to justify when the underlying process is performing to specification. The only rational failure point is component availability. A single unavailable module — the IC670ALG330 — can force a decision that should not need to be made for another decade.

Procurement teams and plant engineers who have navigated this situation consistently report the same outcome: sourcing a verified spare from a specialist distributor extends the operational life of the system by 5 to 10 years at a fraction of the cost of migration. That window is sufficient to align a future upgrade with a planned capital cycle rather than an emergency response.

DriveKNMS operates specifically within this segment of the supply chain. We source, inspect, and hold inventory of obsolete industrial control components for exactly this scenario. The IC670ALG330 units we carry are not pulled from unknown lots — they go through a documented inspection process before being offered for sale.

Condition & Reliability Assurance

Obsolete modules sourced from secondary markets carry inherent risk if not properly evaluated. Our 5-step QA process addresses the failure modes most commonly associated with aged industrial electronics:

• Step 1 – Visual and Physical Inspection: Examination of the module housing, connector pins, and PCB surface for physical damage, corrosion, or evidence of prior field failure.
• Step 2 – Electrolytic Capacitor Assessment: Aged electrolytic capacitors are the leading cause of latent failure in modules stored for extended periods. Each unit is evaluated for capacitor condition, with replacement performed where degradation is identified.
• Step 3 – Pin and Connector Integrity Check: Backplane connector pins are inspected for oxidation, bending, and contact resistance. Corroded or deformed pins are addressed before the unit is cleared.
• Step 4 – Firmware Version Verification: Where accessible, firmware revision is confirmed against known compatible versions for the Series 90 Micro platform to prevent compatibility conflicts on installation.
• Step 5 – Functional Bench Test: The module is powered and tested under controlled conditions to verify output channel response prior to shipment.

Key Features for System Maintenance

How do I know the unit is genuine and not a counterfeit?
All IC670ALG330 units we supply are sourced through traceable channels. Physical markings, PCB construction, and component layout are verified against known-genuine references during inspection. We do not source from unverified bulk lots.

Should I buy more than one unit as a long-term spare?
For any facility where this module is a single point of failure in a production-critical system, holding at least one additional spare is a standard risk mitigation practice. Given that availability of this part will not improve over time, procurement now — while RFQ-reviewed sourcing status exists — is the lower-cost option compared to emergency sourcing under production pressure.

Can you source other IC670 family modules?
Yes. DriveKNMS maintains sourcing capability across the IC670 product family. Contact us with your full bill of materials for a consolidated quotation.
