ABB DSDO115A 3BSE018298R1 Digital Output Module

Description

Hardware and Performance Specifications Auxiliary supply: Powered by VME rack back‑plane, no external power supply required Power consumption: ≤9 W Output channels: 32‑channel galvanic‑isolated digital output Output type: Sink output, 24 V DC Maximum output current per channel: 0.5 A Isolation voltage: Group‑wise galvanic isolation between field‑side and system‑bus circuit Mounting mode: VME Eurocard plug‑in board for Advant subrack Protection class: IP20 Operating temperature: −25 ℃ ~ +60 ℃ 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. 328 × 237 × 30 mm, weight approx. 0.56 kg Certifications: CE approval

Main Functions Receive binary control commands from Advant main controller over VME back‑plane bus. Drive field‑site binary actuators including relays, contactors and solenoid valves via isolated output channels. Provide over‑current protection for each output channel. Support channel‑level diagnosis for output circuit short‑circuit and load fault detection. Front‑panel LED indicators display power‑on status, channel activity and hardware fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects internal circuit faults and reports fault information to the controller. Parameter configuration and channel debugging are completed by ABB Advant engineering software.

Installation Requirement Plug‑in installation inside Advant VME controller subrack. Digital output signal 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 DSDO115A / 3BSE018298R1 matches original project configuration, download complete system configuration file. Perform channel point‑to‑point signal‑loop test and output action verification. 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 Digital‑output‑module spare part for ABB Advant OCS / MasterPiece AC400 automation‑control systems; widely used for binary equipment driving in thermal‑power plants, hydropower plants and petrochemical industries; applied for legacy DCS‑PLC system maintenance and spare‑part replacement.
