Product Introduction
When your heavy-load industrial motor needs smooth ramp-up start control to avoid inrush current impact on the power grid, this control board acts as the core brain of the ABB ASTAT soft starter system.
It features 16-bit high-precision A/D conversion that ensures accurate motor current, voltage and temperature signal acquisition, effectively suppressing start current fluctuations. Its built-in comprehensive fault diagnosis mechanism can quickly identify overcurrent, overheating and phase loss anomalies, triggering immediate protection actions to prevent motor damage.

Field Application & Technical Pitfalls
Critical Industrial Scenarios
- Mining Heavy-Duty Conveyor Motor Control: Executes smooth ramp-up start control for large mining belt conveyors, avoiding mechanical impact and power grid overloading caused by direct motor startup.
- **Water Plant Large Pump Soft Start: Provides precise current-limiting start control for large water supply pumps, eliminating water hammer effect and extending pump equipment service life.
- **Metallurgical Plant Fan & Compressor Control: Acts as the core control unit for metallurgical plant large fan and compressor soft starter systems, ensuring stable and reliable motor start-stop operation.
Non-Negotiable Technical Pitfalls
- ⚠️ Bold Warning 1: Never connect 220V AC power directly to the digital input terminals. The third input channel will instantly burn out the optocoupler isolation circuit, completely disabling signal acquisition function.
- ⚠️ Bold Warning 2: Skipping the pre-commissioning motor parameter matching calibration will leave you with 30% start current overshoot. This unit must be configured with the exact motor rated current and ramp-up time parameters to achieve rated soft start performance.
- ⚠️ Bold Warning 3: Do not use non-matching power connectors with the board. Poor contact will cause intermittent power loss during motor startup, triggering unexpected soft starter shutdown and unplanned production downtime.
A mining plant maintenance team once swapped a DAPC100 control board and skipped the motor parameter calibration. The 35% start current overshoot caused the 400V distribution transformer to trip on overcurrent, resulting in a 2-hour mining conveyor shutdown that cost over $18,000 in lost production.

Quality Control (QC) SOP & Transparency
- Inbound Verification: Cross-check the OEM serial number against ABB’s official part registry, confirm the part number DAPC100 3ASC25H203 matches the factory label, and inspect no bent pins or corrosion on all connector terminals.
- Live Rig Testing: Power the board in a calibrated ASTAT soft starter test bench, apply 220V AC power, and confirm full 24DI/16DO channel operation stability for 2 continuous hours.
- Parameter Testing: Verify 16-bit A/D conversion accuracy stays within ±0.1% of full scale, confirm all soft start logic execution meets factory specifications, and validate all fault diagnosis LED indicators function correctly.
- Final QA & Packaging: Seal the tested control board in a static-shielding anti-static bag, attach a unique QC passed serial label, and nest it in foam padding inside a rigid industrial shipping carton.
Frequently Asked Questions (FAQ)
- Can I hot-swap this control board while the soft starter is running? No. You must first completely cut off the main power supply of the soft starter before replacing the board, otherwise you will face high-voltage electric shock risk and permanent board damage.
- What exact ABB systems is this module compatible with? It works natively with ABB ASTAT series soft starter systems. It will not operate correctly with other brands of soft starters without custom control logic modification.
- How long is the standard warranty for this new surplus unit? 12 months from delivery. It covers all manufacturing defects, but does not extend to units damaged by miswiring, overvoltage, or improper motor parameter configuration in the field.
- How do I tell a genuine OEM unit apart from a refurbished clone? Genuine ABB DAPC100 3ASC25H203 boards have a laser-etched part number on the PCB, not a printed sticker. Clone units almost always fail the 16-bit A/D conversion accuracy test.
- What is the typical lead time for shipment? In-stock units ship within 48 hours. If you require official ABB factory performance test documentation, add 2 extra business days to the turnaround window.
- Can this board replace the older DAPC80 legacy soft starter control board? Well, technically it fits the same installation footprint, but you will need to reconfigure all motor soft start parameters in the system to unlock the full 16-bit high-precision control performance.
