How to Source Discontinued Honeywell and GE Modules

Discontinued control modules require careful identification because legacy families can contain visually similar variants. The most useful first step is preserving every identifier on the original unit.

Keep the original label details

Record the full catalog number, revision, series and any visible suffix. Do not replace the model with a generic description such as communication card or input module.

Share compatible-system context

Include the controller family, rack or application when available. A photo of the connectors and nameplate can help distinguish related legacy versions.

Ask for condition options clearly

State whether used or refurbished alternatives may be considered. Any condition, availability and documentation details should be confirmed for the specific inquiry.

Start with a complete identification record

Discontinued Honeywell and GE modules often appear in legacy control systems where a small suffix or revision changes compatibility. Record the manufacturer, full model number, board or module type, system family, revision, and any markings on the nameplate. A clear photo of the front label and connectors is often more useful than a product name copied from an old spreadsheet.

Check the system relationship

Describe where the part is used: controller rack, remote I/O, communication path, safety system, power section, or monitoring cabinet. Also note whether the request is for an identical replacement, a cross-reference review, or an alternative that will be evaluated by your engineering team. This distinction keeps the inquiry technically honest and avoids treating a possible alternative as a confirmed substitute.

Ask for evidence that supports the decision

Request the available condition description, inspection details, photos, packaging method, documentation, and lead-time estimate for the specific unit. For obsolete parts, availability can change quickly, so the final status should be confirmed by email when the inquiry is reviewed.

Send a parts list when several modules are involved. NANKMOS can organize the request by brand and model so the maintenance team receives a clearer response.
