ABB DSCS131 57310001-LM Serial Communication Module

Description

Hardware and Performance Specifications Auxiliary supply: Powered by VME rack back‑plane, no external power supply required Power consumption: ≤8 W Communication interfaces: Multi‑channel RS‑232 / RS‑485 serial interfaces Supported protocols: ABB proprietary internal serial protocols, compatible with standard asynchronous serial data transmission Mounting mode: VME Eurocard plug‑in board for Advant subrack Protection class: IP20 Operating temperature: −25 ℃ ~ +70 ℃ Storage temperature: −40 ℃ ~ +85 ℃ Humidity: 5‑95 %RH non‑condensing EMC compliance: Comply with IEC 61000‑4 series industrial electromagnetic‑compatibility standards Dimension & weight: approx. 324 × 234 × 30 mm, weight approx. 0.48 kg Certifications: CE approval

Main Functions Expand multi‑channel asynchronous serial communication resources for Advant AC400 DCS controller. Realize bidirectional data transmission between DCS controller and external serial‑interface field devices. Complete serial signal conditioning and surge protection for communication channels. Front‑panel LED indicators display power‑on status, communication traffic and hardware fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects internal circuit faults and serial communication errors, and reports fault information to the main controller. Parameter configuration, baud‑rate setting and communication debugging are completed by ABB Advant engineering software.

Installation Requirement Plug‑in installation inside Advant VME controller subrack. Serial communication cables shall adopt shielded twisted‑pair and be strictly separated from high‑power power cables. Ensure reliable cabinet protective grounding. After module replacement, confirm full part‑number DSCS131 / 57310001‑LM matches original project configuration, download complete system configuration file. Perform serial‑port communication test and verify data interaction with connected external devices. Different hardware revisions cannot be directly interchanged without configuration adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Serial‑communication‑module spare part for ABB Advant OCS / MasterPiece AC400 automation‑control systems; widely used for third‑party device interconnection in thermal‑power plants, hydropower plants and petrochemical industries; applied for legacy DCS‑PLC system maintenance and spare‑part replacement.
