GE ASSY-11993R2 Industrial Control Assembly – Reliable OEM Board for GE Control Racks
The GE ASSY-11993R2 is an OEM board-level assembly designed for GE control cabinets and rack systems. From my experience, this type of module is typically used as an internal interface or signal-handling board, bridging the system backplane and connected subassemblies. If you’re maintaining a legacy GE platform, it seems to be a straight replacement option that helps you keep the installed base running without re-engineering the entire panel.

- Industrial Temperature Tolerance – Built for cabinet environments found in plant floors and utility rooms.
Technical Specifications
| Brand / Model | GE ASSY-11993R2 |
| HS Code | 853890 (Parts for electrical control apparatus) |
| Power Requirements | Supplied via system backplane; typically low-voltage logic rails (e.g., 5 VDC) with control rail support (e.g., 24 VDC) depending on host system |
| Dimensions & Weight | Board-level assembly for GE rack/cabinet; nominal weight under 0.5 kg |
| Operating Temperature | 0 to 60 °C (cabinet-installed, non-condensing atmosphere) |
| Signal I/O Types | Internal backplane and ribbon/edge connections; no direct field-wiring terminals on the bare assembly |
| Communication Interfaces | Host backplane interface; external fieldbus handled by the system controller where applicable |
| Installation Method | Rack/cabinet mount inside GE control enclosure; secured via card guides and fasteners; ESD-safe handling required |
Application Fields
You might notice that assemblies like the ASSY-11993R2 are commonly deployed where GE control architectures are already standard. Typical scenarios include:
- Power generation control cabinets (turbine auxiliaries, balance-of-plant panels)
- Oil & gas process skids and compressor stations
- Discrete and hybrid manufacturing lines using GE racks
- Water and wastewater control rooms with GE installed base
- Test benches and retrofits where maintaining GE interfaces is critical
Advantages & Value
- Reduced Downtime – Drop-in compatibility means faster swap-outs during outages.
- Lifecycle Support – Ideal for sustaining legacy assets without a full system redesign.
- Cost Control – Keeps existing wiring and cabinet layouts intact, which typically cuts installation costs.
- Technical Backing – We provide guidance on identification, fit, and safe handling—especially useful when documentation is limited.
Installation & Maintenance
- Cabinet Environment: Install in a clean, dry, non-condensing enclosure with adequate ventilation; maintain ambient 0–60 °C.
- Wiring & Handling: De-energize the rack, follow ESD procedures (wrist strap, antistatic bag). Verify keyed connectors before seating.
- Mounting: Use the original card guides and fasteners; do not over-torque. Confirm backplane alignment before power-up.
- Routine Care: Inspect quarterly for dust buildup; gently clean with dry, ESD-safe methods. Check connectors for oxidation or looseness.
- Firmware/Config: If applicable in your system, ensure the host controller configuration matches the assembly revision.
Quality & Certifications
- Manufactured to GE quality standards; typically used in CE-marked control panels
- RoHS compliance may vary by revision and application (legacy exemptions may apply)
- UL/CSA recognition aligned with the host system where applicable
- 365-day warranty from our side for materials and workmanship
Supporting Components (for a smooth installation)
- GE Rack/Chassis: The compatible enclosure that provides mechanical support and the backplane power/signals.
- Backplane Harness/Connectors: Keyed ribbon or edge connectors used to mate the ASSY-11993R2 to the system bus.
- Control Power Supply Module: Supplies the 5 VDC logic and 24 VDC control rails used by the rack.
- Cabinet Fan/Filter Kit: Helps maintain temperature and reduce dust, extending board life in many cases.
One thing I appreciate is how quickly maintenance teams can swap this kind of assembly. A utilities customer told us they replaced a failed board with an ASSY-11993R2 during a short plant pause—total downtime under 35 minutes, largely because it fit the existing guides and plugged straight into the backplane.
If you’d like, share the rack ID or a photo of the installed slot and we’ll double-check fit and revision compatibility before you place the order.
