Description
Product Overview
The ABB CMA120, commonly listed with order number 3DDE300400, is associated with the legacy Synpol D control platform. It is marketed as a basic controller panel for industrial control and generator-control installations. In this context, its purpose is to provide a local interface for viewing operating information and interacting with the installed control system. The exact functions available depend on the original panel configuration and the equipment it was designed to operate with.
For maintenance and procurement teams, the main consideration is compatibility with the existing installation. A replacement panel must match the complete order code, rear connections, control-system configuration, and required operator functions. Available reseller descriptions conflict on supply voltage, dimensions, communication interfaces, and even some functional details. Those values should not be used as engineering design data without confirmation from the nameplate or an applicable ABB manual.
The ABB CMA120 is best approached as a legacy spare rather than a generic PLC or universal HMI. Before placing an order, request photographs of the actual unit, confirmation of its complete part number, and a description of any testing performed. For refurbished equipment, ask whether the display, keys, indicators, and communication functions were checked under operating conditions. A successful power-on test alone does not demonstrate that the panel will communicate correctly with the plant’s control system.
Product Introduction
The CMA120 is associated with ABB Synpol D installations, including legacy generator-control applications. Its local operator role can make it important during commissioning, routine operation, troubleshooting, and replacement of aging control hardware. The precise controls and displayed process values should be confirmed against the specific system in which the unit is installed.
During replacement planning, record the old panel’s label details and connector layout before disconnection. Confirm the required auxiliary supply and wiring from the original documentation, isolate the equipment according to site procedures, and verify local indications and control functions before returning the installation to service. Do not rely on generic online wiring instructions where they conflict with the site’s approved drawings.

Sources identify CMA120 3DDE300400 as a Synpol D basic controller panel, but the available specifications are inconsistent.
Important model-number distinction: ABB listings also use the designation CMA120 for a different item, order number 3BSE013240R1, described as a communication module adapter for AC 800M. Do not treat that adapter as equivalent to the Synpol D panel, 3DDE300400. Confirm the full order number before procurement.

Frequently Asked Questions
1. What is the ABB ?
The with order number 3DDE300400 is listed as a basic controller or operator panel associated with ABB Synpol D installations.
2. Is a PLC module?
The listings reviewed primarily describe the 3DDE300400 version as a controller or operator panel. Verify the exact hardware identity before classifying it as a CPU, I/O module, or HMI.
3. What is the operating voltage?
Available listings disagree. Do not assume 24 VDC or 220 VAC from the model name alone. Check the unit’s rating label and applicable wiring documentation.
4. Can it be used with ABB AC 800M?
Do not infer compatibility from the designation alone. The Synpol D unit with order number 3DDE300400 is distinct from the communication module adapter listed as 3BSE013240R1.
5. What should be checked before ordering a replacement?
Confirm the complete order number, hardware revision if present, supply rating, connector arrangement, mounting dimensions, and intended control-system application. Request actual-unit photographs and available test records.
6. Is refurbished stock suitable for a plant shutdown spare?
It may be suitable if the exact variant is confirmed and the supplier provides meaningful functional-test evidence. For critical applications, establish acceptance criteria before shipment and arrange a documented commissioning test.
Procurement Recommendation
For the ABB , the first purchasing requirement is positive part-number identification. The designation is used in listings for different hardware, and the specifications published for the 3DDE300400 Synpol D panel are not consistent enough to establish electrical compatibility from reseller descriptions alone.
Before requesting a quotation, match the old unit’s full order number and nameplate against the replacement. Require confirmation of condition, connector compatibility, supply rating, return terms, and test scope. If the installed unit is actually marked 3BSE013240R1, use that complete number in the procurement request instead of ordering the Synpol D panel listed as 3DDE300400.
