The ABB 3ASC25H204 DAPU100 Replacement Control Module is the I/O control board (Control Board, I/O) of the ABB DARA 1000 / DARA 2000 thyristor AC drive systems. Working alongside the DAPC100 main control board (3ASC25H203), it provides the input/output signal interface between the drive control electronics and the external control circuits — handling command, feedback, and status signals for the DARA crane and hoist drive family.
Key Features
- I/O control board for ABB DARA 1000 / DARA 2000 thyristor AC drive systems
- Companion board to the DAPC100 main control board (3ASC25H203)
- Handles input/output signal interfacing between drive control logic and external circuits
- 24 V DC supply (24 V DC ±10%)
- Isolated I/O channels (16 input / 16 output per service data)
- Compact plug-in board (approx. 0.08 kg) for DARA drive cubicle mounting
- Swedish-made (ABB, DARA drive family)

Installation Notes
- De-energize the DARA drive cubicle and confirm the DC-link is discharged before handling the board.
- Install the DAPU100 in its designated I/O board slot; seat the connector fully and secure the board.
- Verify the 24 V DC supply (within ±10%) before power-up.
- Connect the external command / feedback / status wiring per the DARA wiring diagram; check isolation of I/O channels.
- After commissioning, verify I/O signal exchange with the DAPC100 control board via the drive’s diagnostics before returning the drive to service.
Common Questions
What is the DAPU100 used for? It is the I/O control board of the ABB DARA drive system: it interfaces input/output signals (commands, feedback, status) between the drive control electronics and the external control circuits, working with the DAPC100 main control board.
Which systems use it? ABB DARA 1000 / DARA 2000 thyristor AC drive systems, used in crane and hoist applications. The 3ASC25H203 DAPC100 is its companion control board.
What power does it need? 24 V DC ±10%.
