ABB DATX110 3BSC980004R78

The ABB DATX110 is an industrial control and interface board associated with ABB’s older automation and process-control equipment. The commonly referenced board designation is 3ASC25H209, while 3BSC980004R784 appears in multiple industrial-part references as the associated product/base number. Your supplied 3BSC980004R78 appears to be a shortened form of this number, so the exact nameplate should be checked before ordering.

Core Functions

• Provides interface/control functions within ABB industrial automation equipment.
• Interfaces with associated process-control circuitry and field signals.
• Designed as a replaceable electronic board for ABB legacy control systems.
• Used together with the corresponding ABB hardware and wiring architecture rather than as a standalone PLC CPU.

ABB documentation from its legacy ASTAT/PROCESS I/O systems also identifies DATX110 in electrical drawings, confirming its use within ABB process-control hardware. 

Design Features

• ABB industrial-grade PCB design.
• Compact board-level construction for cabinet-mounted automation equipment.
• Identified by multiple related numbers, including DATX110, 3ASC25H209, and references to 3BSC980004R784.
• Because different sources associate these numbers with somewhat different descriptions, part-number and PCB-label verification is particularly important. 

Hardware Composition
Typical identification information may include:

Typical Applications
DATX110-related hardware can be found in ABB industrial automation installations, particularly legacy process-control, ASTAT, and industrial drive/control systems. ABB's own documentation contains DATX110 references in process I/O electrical drawings. 

Maintenance Considerations
Before replacement, verify:

1. Complete ABB part number on the original label.
2. PCB identification, especially 3ASC25H209 if present.
3. Connector arrangement and hardware revision.
4. Compatibility with the existing ABB control system.
5. Whether the replacement is new, refurbished, or previously installed.

For obsolete ABB boards, matching the exact hardware revision and part number is generally more important than relying on the DATX110 model alone.

Overall Evaluation
The ABB DATX110 3BSC980004R78 should be treated as an ABB legacy industrial automation board/assembly. Because online references commonly show the longer designation
