Description
Product Introduction
When an established control system develops a hardware fault, replacing the failed assembly with a part of the correct revision can be less disruptive than changing the surrounding controls. GE 04220HL21204A appears in industrial spare-part catalogs, but the published descriptions do not consistently identify its hardware function. That distinction matters: an I/O card, an IPC assembly, and a controller module are not interchangeable simply because they share a manufacturer name.
For procurement, treat GE 04220HL21204A as a model-specific identification that still requires technical confirmation. Match the full part number and revision against the installed assembly, verify connector and mounting details, and request test evidence and condition grading before committing to a replacement.
Key Technical Specifications
| Parameter | Available information |
|---|---|
| Model number | 04220HL21204A |
| Manufacturer attribution | General Electric (GE), as listed by parts catalogs |
| Product family | Not confirmed |
| Hardware category | Conflicting descriptions: I/O module, IPC/control module |
| Supply voltage | Unverified for this exact part |
| Input/output count | Unverified |
| Communication interface | Unverified |
| Installation method | Confirm against the actual assembly and host equipment |
| Operating temperature | Not verified from a manufacturer datasheet |
| Firmware or configuration requirements | Must be checked against the installed system |
One catalog associates the number with a GE Series 90-30 discrete I/O module, while other listings describe a control module or industrial computer. Those descriptions are not sufficient to establish the correct specifications or compatibility.

Application Scenarios & Pain Points
The main procurement risk is ordering a part based on an incomplete catalog description rather than the identity of the installed assembly.
- Legacy system maintenance: Match the full part number and any revision suffix to the failed unit before sourcing a spare.
- Unplanned equipment downtime: Confirm the component’s actual role in the system so the replacement addresses the fault rather than introducing a second mismatch.
- Obsolete hardware sourcing: Ask the supplier to document whether the unit is new, unused surplus, refurbished, or previously installed.
- Pre-installation verification: Compare connector layout, board markings, mounting arrangement, and host-system documentation before scheduling a replacement.
A practical check: request clear photographs of the front label, PCB identification, connectors, and revision markings. These details can help resolve discrepancies between catalog descriptions and the physical component.
Related Products and Identification References
The following are useful verification references, not confirmed direct replacements.
- IC693 Series 90-30 I/O modules — relevant only if the installed assembly is confirmed to belong to the Series 90-30 PLC family.
- GE industrial control computer assemblies — investigate only if the part is confirmed as an IPC or computer-related assembly.
- GE control-system interface modules — a broad category; exact family and interface must be established first.
- GE replacement assemblies with matching suffixes — compare the complete catalog number and revision, not just the shared prefix.
Do not treat these categories as interchangeable. No direct replacement for 04220HL21204A has been verified from the available documentation.
Engineer’s Guide: Three Replacement Checks
1. Confirm the component identity. Compare the part number on the physical label with the equipment bill of materials and the original drawing. Do not rely on a supplier’s product title alone.
2. Verify electrical and mechanical compatibility. Confirm supply requirements, connectors, pin assignments, mounting, and host-system support from the correct technical documentation. Do not assume 24 VDC or a particular I/O configuration without evidence.
3. Request traceable condition and test information. For a new-surplus or refurbished unit, ask for label photographs, revision details, inspection results, and the written warranty terms. A generic statement that the part has been tested does not establish that every required function was checked.
Frequently Asked Questions
What is GE 04220HL21204A?
It is a GE-attributed industrial spare-part number, but the available catalog descriptions conflict on whether it identifies an I/O module or a control-computer-related assembly. The exact function needs confirmation before a definitive product specification can be published.
Does 04220HL21204A operate at 24 VDC?
One catalog describes the part as an industrial control computer with a 24 V, 3.4 A designation, but this has not been confirmed by a manufacturer datasheet for the exact part. Verify the nameplate and wiring documentation before applying power.
Is it compatible with a GE Series 90-30 PLC?
A supplier listing associates the part with the Series 90-30 family, but that association is not enough to establish compatibility. Confirm the exact module type, rack, CPU, and system documentation first.
Can I use a similar GE part number as a replacement?
Not without checking the full part number, revision, electrical characteristics, connectors, and intended system. A similar-looking part may have a different function or pinout.
How can I verify that a supplied unit is genuine and correctly identified?
Request photographs of the original manufacturer’s label and PCB markings, plus any available traceability records. Compare those details with the removed part and the equipment documentation.
What should I confirm before requesting a quotation?
Provide the complete model number, photographs of the label and assembly, the host equipment model, the installed revision, and the required condition. Ask the supplier to state the test scope, warranty, and dispatch lead time in writing.
Is the part still in production?
I could not verify an authoritative manufacturer lifecycle notice for this exact number. Treat current production status and availability as unconfirmed until the manufacturer or a qualified supplier provides supporting documentation.
Procurement recommendation: Before publishing a definitive specification sheet for GE 04220HL21204A, establish the actual hardware type from a label photo or the original equipment documentation. This is the key step needed to avoid presenting unverified electrical ratings or compatibility claims as facts.
