Sagemcom 252721117AC | Industrial Communication Module

Description

Key Technical Specifications

• Procurement caution: The voltage, communication interfaces, temperature range, and IP rating above appear in secondary listings, but I could not verify these values against a reliable Sagemcom technical document for 252721117AC. Some sources also contradict one another about the module’s actual function.

That uncertainty matters. One source calls it a processor module, another an automation control module, and another a function/communication module. I would not publish a detailed pinout, protocol list, port count, or exact power specification as fact without additional OEM documentation.

Application Scenarios & Pain Points

The main procurement risk here is misidentification, not installation difficulty. When an obscure OEM assembly fails in a running plant, a generic description such as “communication module” is not enough to select a replacement.

• Legacy automation equipment: Potentially applicable as an OEM control or communication assembly where 252721117AC is already installed.
• PLC/DCS spare holdings: Useful as an exact-match replacement candidate when the plant BOM identifies this part number.
• Control-system communication: Several secondary references classify the device as a communication-related module, but the exact protocol should be confirmed from the original system documentation.
• Emergency replacement: The full nameplate and connector arrangement should be used as the acceptance criteria rather than a generic catalog description.

Brief Field Case

For an obsolete control assembly with limited documentation, a technician may receive three different descriptions for the same part number: processor, I/O module, and communication module. That is exactly when stopping to photograph the board and connectors pays off. A ten-minute identification check can prevent installing an electrically incompatible spare.

Related Products

Because the 252721117AC documentation is poorly standardized in publicly available sources, related models should be treated as identification references, not automatic substitutes.

• 252720938AB — A related Sagemcom-numbered industrial automation assembly frequently listed alongside 252721117AC. Do not assume functional interchangeability.
• 252721013AF — Another Sagemcom-numbered industrial control component appearing in the same spare-parts catalogs. Exact interface and system position should be checked.
• 252721117AC — Subject part number; the correct choice when the installed system BOM specifically calls for this assembly.
• GE 369-HI-RMFEHE — Some secondary listings associate 252721117AC with motor-management relay terminology, but this cross-reference is not sufficiently reliable to approve as a direct equivalence.
• ABB PFEA111 Series — Appears in the same industrial spare-parts inventories but belongs to a different tension-control application and should not be treated as a functional substitute.
• GE IC670ALG310-JA — A GE analog output module frequently cataloged near this part number; it is a completely different I/O architecture and is only relevant as an example of an alternative plant automation component.
• FOXBORO FBM233 P0926GX — Ethernet communication hardware from another control-system family; functionally distinct and not a drop-in replacement.
• VM600 200-Series I/O modules — Vibration-monitoring hardware found in similar industrial inventories; applicable to machinery monitoring rather than generic control-module replacement.

The Engineer’s Guide: Field Pitfalls to Avoid

WARNING 1 — Do not trust the generic product description.

Secondary listings disagree substantially about whether 252721117AC is a processor, communication module, I/O module, or function module.

How to avoid it: Match the complete part number + nameplate + physical interface + cabinet location. Do not approve a replacement from the title alone.

WARNING 2 — Do not assume the reported 12–24 VDC specification is confirmed.

That voltage range appears in secondary listings, but I could not establish it from dependable OEM documentation for this exact part.

How to avoid it: Verify the actual supply requirement from the machine schematic, terminal drawing, or original equipment documentation before energizing a replacement.

WARNING 3 — Avoid unverified cross-references.

The number 252721117AC has been associated online with several unrelated functional descriptions, including a motor-management relay.

How to avoid it: Request a photograph of the actual replacement unit, including its label, connectors, PCB markings, and revision. If the seller cannot provide that evidence, treat the part as an identification-risk purchase.

Frequently Asked Questions (FAQ)

What is Sagemcom 252721117AC?

252721117AC is an OEM-specific industrial automation part number, but its exact function is not sufficiently documented in reliable public technical literature. Secondary sources describe it variously as a processor, communication, control, I/O, or function module.

For an engineering BOM, the installed system documentation should take precedence over generic web descriptions.

Is 252721117AC a PLC CPU?

It should not be classified as a PLC CPU without further identification. One secondary listing calls it a processor module, but other sources use different functional descriptions.

If the application is safety-critical, verify the original system architecture and board-level markings before replacement.

What voltage does 252721117AC require?

Some secondary listings state 12–24 VDC, while the available documentation does not provide enough reliable evidence for me to treat that value as an OEM-confirmed specification.

Do not energize a replacement based solely on this number. Verify the machine schematic or original technical documentation first.

Is 252721117AC the same as 252720938AB?

No direct equivalence has been established. Both numbers appear in industrial automation inventories, but they should be treated as separate part numbers unless the original equipment manufacturer provides a formal substitution.

How can I verify an authentic replacement?

Ask for:

• Complete nameplate photograph.
• Exact 252721117AC part number.
• Hardware revision.
• Serial number or production marking.
• Front and rear photographs.
• Connector arrangement.
• PCB identification markings.
• Functional test report.
• Power-on test results.
• Warranty/return terms.

For this particular part, physical identification is more important than a generic datasheet because publicly available descriptions conflict.

What should I test before installing a refurbished 252721117AC?

At minimum, verify the correct supply interface, connector condition, board condition, communication or I/O function applicable to the host system, and any diagnostics available from the equipment.

If the original machine is still operational, capture its existing configuration and diagnostic state before removing the failed unit. That gives the commissioning technician a reference point when the replacement is installed.
