Product Detail

ABB DAPC100 with part number 3ASC25H203 is the core main control motherboard for ASTAT series soft starter, responsible for thyristor trigger control, signal acquisition, bus communication and fault diagnosis, matching DARA1000/1001/1010 soft start units for industrial motor slow start and protection control

Product Overview

Model: DAPC100
Part Number: 3ASC25H203
Brand: ABB
Series: ASTAT Soft Starter Control System
Type: Main Processor & Trigger Control Board
Function: It serves as the central operation core of ABB ASTAT soft starter. It receives parameter configuration from upper computer or local panel, outputs trigger pulses to control thyristor modules to realize stepless voltage boosting and slow start of three-phase asynchronous motor, avoids large impact current during direct startup. It collects real-time voltage, current and temperature signals inside the equipment, executes overload, overcurrent, phase loss, overheat and short-circuit protection logic, and completes data interaction with upper monitoring system via multiple communication interfaces. It needs to be matched with DAPU100 process I/O board and DATX130 signal cable to form a complete soft start control unit.

Core Features

Multi-group isolated communication interfaces

X5 port: RS232/RS485, connects to PC for parameter setting and program debugging
Three optical fiber channels: vertical uplink with main controller, horizontal interconnection between multiple soft starters, internal communication with DAPU100 I/O module
X7/X8 dedicated terminals: wiring connection to thyristor power modules for trigger signal transmission

Built-in complete electrical protection mechanism, automatically lock output and record fault codes when abnormal working conditions occur
Onboard memory chip stores startup curve, protection threshold and running historical data, supports one-click parameter backup and recovery
PCB adopts conformal coating technology, dustproof, moistureproof and anti-electromagnetic interference, adapts to long-term operation in industrial power distribution cabinets
Supports hot swap replacement after power off, no complicated program rewriting when replacing the same model board, quick on-site maintenance
Compatible with ASTAT Tool dedicated configuration software for remote parameter modification and equipment status monitoring
