Product Overview
The ABB DAPC100 3ASC25H203 is a control board used in ABB ASTAT digital drive systems. ABB product documentation identifies the base 3ASC25H203 family as the DAPC 100 control board with CMT memory stick, while specific ordering variants include 3ASC25H203-12 and 3ASC25H203-57. The -12 version is associated with the DARA 2000 system, while the -57 version is listed for DARA 1000, DARA 1001, and DARA 1010 applications. ABB classifies these assemblies under ASTAT boards, control units, and power supplies.
This is a control-system component rather than a conventional PLC I/O module. The CMT memory stick provides a practical means of retaining or transferring drive-related configuration information. Because the 3ASC25H203 family has multiple variants, the complete suffix should be checked before replacement. Personally, I would verify the board label, CMT device, installed ASTAT drive type, and firmware or parameter configuration rather than treating every DAPC 100 assembly as interchangeable.

Key Features and Benefits — DAPC100 3ASC25H203
- Designed for ABB ASTAT digital drive control systems.
- Provides central control-board functionality within the applicable drive architecture.
- Includes support for a CMT memory stick for configuration or service data.
- Available in multiple application-specific variants.
- Suitable for maintaining older DARA and ASTAT drive installations.
- Compact board construction is practical for planned maintenance and spare-parts inventory.
- Exact suffix matching reduces the risk of installing an incompatible control revision.
The suffix is important here. ABB lists different DARA applications for the -12 and -57 versions, so a generic “DAPC100” description is not enough for a reliable replacement decision.

Installation and Maintenance — DAPC100 3ASC25H203
Before replacement, isolate the ASTAT drive and follow the applicable ABB electrical safety procedure. Record the installed board suffix, hardware revision, parameter configuration, and CMT memory-stick information before removal. Do not assume the replacement board contains the same application data.
Inspect connectors, mounting points, and the CMT interface for contamination or mechanical damage. After installation, verify all control connections, reload or confirm the required parameters, and perform drive diagnostics before enabling the power stage.
For warehouse storage, protect the board against ESD, moisture, dust, and mechanical shock. Keep the CMT memory device with the correct board when configuration traceability is required.
Product Warranty — DAPC100 3ASC25H203
Warranty depends on whether the unit is supplied as new, refurbished, repaired, or used. The purchase record should identify the exact ABB suffix, hardware revision, CMT status, test condition, and warranty period. Actual-unit photographs are recommended because the 3ASC25H203 family contains multiple variants.
The ABB DAPC100 3ASC25H203 is best managed as an ASTAT control-board spare, with the full ordering suffix verified against the installed DARA system before installation.
