GE IC670MDL930J Discrete Output Module – Obsolete Series 90 Micro Spare Part

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Electrical parameters not listed above are not independently verified by DriveKNMS. Specifications should be cross-referenced against the original GE Fanuc IC670MDL930J datasheet prior to installation.

Solving the Discontinued Hardware Crisis

The GE Fanuc Series 90 Micro platform was deployed extensively across light manufacturing, water treatment, building automation, and small-scale process control throughout the 1990s and 2000s. Many of these installations remain operational today — not because the hardware is new, but because the control logic embedded in them represents years of tuning, and the cost of replacing a functioning system is difficult to justify to any finance committee.

The IC670MDL930J sits at a critical junction in these systems. As a relay output module, it handles the physical switching of field devices — motors, solenoids, indicators, and actuators. When it fails, the PLC cannot command the process. There is no software workaround. The module must be replaced with an identical unit, or the entire rack must be redesigned around a different I/O architecture — a project that touches wiring, programming, and commissioning simultaneously.

Condition & Reliability Assurance

DriveKNMS applies a 5-step inspection protocol to all obsolete modules before they are offered for sale. This process is designed around the specific failure modes that affect aging industrial electronics:

• Step 1 – Visual and mechanical inspection: Physical examination of the housing, connector pins, and PCB surface. Pin corrosion, bent contacts, and cracked housings are grounds for rejection at this stage.
• Step 2 – Electrolytic capacitor assessment: Aged electrolytic capacitors are the most common cause of latent failure in modules that have been in storage or light service for extended periods. Capacitors showing signs of bulging, leakage, or elevated ESR are flagged.
• Step 3 – Relay contact verification: For relay output modules, contact resistance and switching integrity are tested. Welded or high-resistance contacts are disqualifying defects.
• Step 4 – Firmware and label verification: The revision suffix (in this case, suffix J) is confirmed against the physical label and, where possible, against internal revision markers. Mismatched revisions can cause compatibility issues in some rack configurations.
• Step 5 – Functional power-on test: Where test fixtures are available for the IC670 platform, modules are powered and output switching is verified under load conditions before packaging.

Key Features for System Maintenance

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Should I buy more than one unit?
For any facility running Series 90 Micro hardware with no planned migration in the next three to five years, holding a minimum of two spare output modules per active rack is a reasonable baseline. The IC670MDL930J is becoming increasingly difficult to source. current sourcing status does not guarantee future availability.

Can this module be used in a different GE PLC family?
The IC670MDL930J is specific to the IC670 (Series 90 Micro) I/O family. It is not compatible with Series 90-30 (IC693) or Series 90-70 (IC697) racks without an adapter, which does not exist as a standard product. Do not attempt cross-family substitution without engineering review.
