Product Overview

• PN:DSPC406｜Brand:ABB｜Series:Advant Master S400 Remote DCS｜Type:S400 Local Processor Module
• Definition:Specialized local processing core matched for ABB classic S400 distributed remote I/O stations, executes on-site real-time interlock logic, signal filtering and local sequence control independently without relying on central main CPU, communicates upward to Advant 410/450 main controller via MasterFieldbus bus, coordinates DSDX404/DSDX452 mixed I/O modules to collect field switch signals and drive on-site actuators, core original spare for aging S400 remote cabinet overhaul and local controller failure replacement

Core Features

• Independent real-time control kernel, supports offline local logic operation; keeps basic safety interlock running even if communication with central CPU is interrupted
• Built-in MasterFieldbus bus communication circuit, supports redundant dual-bus transmission to avoid signal loss during single cable fault
• Integrated hardware self-diagnosis system, front panel multi LED indicators for power, running status, bus link, logic alarm and module fault fast on-site troubleshooting
• Optimized signal filtering algorithm, suppresses contact bounce and electromagnetic interference from power, petrochemical, metallurgy harsh workshop environment
• Dedicated plug-in structure perfectly matched S400 rack backplane, supports hot swap for maintenance without shutting down entire remote station
• Compatible with full range S400 series DI/DO/AI/AO expansion modules for flexible field signal capacity expansion

Technical Specs

• Auxiliary supply:24VDC ±10% control power supply
