Main Functions
- DAPI100 (3AST000929R109) is the dedicated Ethernet communication interface eurocard board for ABB ASTAT soft‑starter system. It provides Ethernet TCP/IP connection for DAPC100 main control processor board.
- Realizes data exchange between ASTAT soft‑starter and upper‑level monitoring system: uploads motor running parameters, start‑stop status, fault alarm and event log; receives remote control commands from SCADA / host system.
- Implements galvanic isolation between Ethernet network and soft‑starter internal control bus, effectively restraining external network interference and improving system anti‑interference performance.
- LED status indicators display module power status and Ethernet link‑active status for on‑site inspection and fault diagnosis.
- Typical field failure symptoms
‑ Ethernet link failure, cannot establish network connection with upper system
‑ No data transmission between DAPI100 and DAPC100 main board
‑ Intermittent communication dropout during soft‑starter operation
Common root causes: 24 VDC power supply abnormality, Ethernet cable damage, backplane connector poor contact, onboard network component ageing, cabinet dust and moisture contamination.
- Pure maintenance‑oriented spare‑part component, only for repair and replacement of existing legacy ASTAT soft‑starter installations; not suitable for new‑project engineering deployment.
Typical Applications
- Spare‑part replacement for DAPI100 Ethernet communicator board inside ABB ASTAT soft‑starter rack.
- Troubleshooting scenarios: soft‑starter Ethernet communication breakdown, remote monitoring data loss.
- Preventive‑maintenance spare‑part inventory for water‑treatment, cement, mining, chemical plants equipped with ASTAT soft‑starter units.
- Hardware refurbishment for decommissioned ASTAT soft‑starter assemblies.
