ABB DSMB127 57360001-HG Memory Board

Description

Hardware and Performance Specifications Auxiliary supply: Powered by VME rack back‑plane, no external power supply required Power consumption: ≤7 W Core function: System memory capacity expansion for AC400 controller Memory type: Industrial non‑volatile memory for program and parameter retention 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 × 22.5 mm, weight approx. 0.40 kg Certifications: CE approval

Main Functions Expand available memory resources for Advant AC400 DCS main controller. Store user application programs, process configuration parameters and important process‑related data. Realize data retention function under power‑off condition for key system parameters. Front‑panel LED indicators display power‑on status and hardware fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects internal circuit faults and memory access errors, and reports fault information to the main controller. Memory‑relevant parameter configuration and diagnosis are completed by ABB Advant engineering software.

Installation Requirement Plug‑in installation inside Advant VME controller subrack. Ensure correct slot position matching according to original project configuration. After module replacement, confirm full part‑number DSMB127 / 57360001‑HG matches original project configuration, download complete system configuration file and perform memory resource identification test. 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 Memory‑expansion‑board spare part for ABB Advant OCS / MasterPiece AC400 automation‑control systems; widely used for controller memory capacity upgrade in thermal‑power plants, hydropower plants and petrochemical industries; applied for legacy DCS‑PLC system maintenance and spare‑part replacement.
