ABB 3ASC25H204 DAPU100
Product introduction
The 3ASC25H204 DAPU100 is a specialized drive adapter unit from ABB, engineered to serve as a bridge between ABB’s ACS600 and ACS800 frequency converters and external control systems. As a key accessory in ABB’s drive connectivity portfolio, 3ASC25H204 DAPU100 facilitates the integration of advanced control signals—including encoder feedback and high-speed digital commands—that standard drive interfaces may not support natively.
Designed for industrial robustness, 3ASC25H204 DAPU100 provides signal conditioning and secure connectivity, ensuring accurate transmission of critical control data between the drive and devices like motion controllers, PLCs, or position sensors. Its compact form factor makes it suitable for space-constrained control cabinets, while compatibility with both legacy and newer ABB drives ensures versatility across various automation setups. Whether deployed in precision motor control applications such as conveyors with positioning requirements or machinery requiring closed-loop speed regulation, 3ASC25H204 DAPU100 enhances drive functionality by enabling seamless communication with external systems.
Core advantages and technical highlights
Encoder feedback integration: 3ASC25H204 DAPU100 supports encoder signals up to 1024 pulses per revolution (ppr), enabling closed-loop speed and position control when paired with ACS600/ACS800 drives. This capability is critical in applications like material handling conveyors that require precise synchronization, where the adapter converts encoder data into a format the drive can use to adjust motor speed in real time. Unlike basic terminal boards such as 3ASC25H214 DATX130, which lack encoder support, 3ASC25H204 DAPU100 unlocks advanced motion control capabilities.
Dual power redundancy: The adapter draws both 5 V DC (for logic circuits) and 24 V DC (for signal conditioning) directly from the drive, eliminating the need for external power supplies and reducing potential failure points. This integrated power design simplifies installation and ensures that critical signal paths remain active as long as the drive is operational—an essential feature in safety-critical applications like elevator drive systems, where unexpected signal loss could lead to operational disruptions.
High-density connectivity: With a 37-pin D-sub external interface, 3ASC25H204 DAPU100 consolidates multiple signal types—including 8 digital inputs, 6 digital outputs, 2 analog inputs, and encoder lines—into a single connection point. This reduces wiring complexity compared to individual terminal connections, making it easier to troubleshoot and maintain. In a packaging machine with ACS800-driven motors, this consolidated interface simplifies connecting both the main PLC commands and the product position encoder, streamlining the overall system architecture.
Backward compatibility: 3ASC25H204 DAPU100 is specifically designed to work with older ACS600 drives, allowing facilities with legacy systems to upgrade their control capabilities without replacing the entire drive. For example, a manufacturing plant using ACS600 drives in its production line can add 3ASC25H204 DAPU100 to integrate modern position sensors, enabling more precise control over material feeding without incurring the cost of a full drive replacement. This compatibility extends the lifecycle of existing automation investments.
Typical application scenarios
In a bottling plant’s labeling machine, 3ASC25H204 DAPU100 connects an ACS800 drive to a rotary encoder mounted on the labeling drum and a PLC. The adapter converts the encoder’s 512 ppr signal into a format the drive uses to maintain precise drum speed, ensuring labels align with bottle positions. Digital inputs via 3ASC25H204 DAPU100 receive start/stop commands from the PLC, while digital outputs send status signals back, creating a closed-loop control system. This setup, which would be difficult to achieve with a basic terminal board like 3ASC25H214 DATX130, reduces label misalignment rates by over 90%.
In a metal processing facility’s rolling mill, 3ASC25H204 DAPU100 integrates an ACS600 drive with a tension sensor and a motion controller. The adapter transmits tension feedback (via analog input) and encoder data from the roll motor to the controller, which adjusts the drive setpoint accordingly. This closed-loop control, enabled by 3ASC25H204 DAPU100, maintains consistent material thickness across the rolling process, improving product quality and reducing waste compared to open-loop systems.

Installation, commissioning and maintenance instructions
Installation preparation: Mount 3ASC25H204 DAPU100 on a 35 mm DIN rail or directly to the panel using the provided hardware, ensuring 40 mm clearance for wiring. Connect the drive-side 24-pin connector to the ACS600/ACS800 drive’s accessory port, ensuring a secure latch engagement. Wire external devices to the 37-pin D-sub connector using shielded twisted-pair cable (0.25-0.5 mm² for signal lines); ground cable shields at the adapter end. Verify that the drive is powered off during installation to prevent electrical damage. Use a torque screwdriver set to 0.3 Nm for terminal connections.
Maintenance suggestions: Inspect 3ASC25H204 DAPU100 quarterly for loose connectors, dust accumulation, and corrosion on the D-sub pins. Clean the adapter with compressed air—avoid contact with liquids or abrasive materials. Test encoder signal integrity semi-annually using an oscilloscope to verify pulse clarity, ensuring no signal degradation. Check isolation resistance annually with a megohmmeter (2 kV for 1 minute) to confirm it remains above 50 MΩ. If communication errors occur, first inspect the drive-to-adapter cable for damage before replacing the unit—use only ABB-certified replacements to maintain compatibility.
