ABB 1MRS050729 Communication Interface Module

Description

Hardware and Performance Specifications Auxiliary supply: Powered by IED internal back‑plane bus Communication interfaces: Ethernet port (copper or optical fiber LC connector according to variant); support IEC 61850, Modbus‑TCP protocols Mounting mode: Plug‑in slot‑mount communication card for Relion 615‑series IED 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 EMC standards and IEC 60255 relay standards Dimension & weight: approx. 145 × 95 × 25 mm, weight approx. 0.38 kg Certifications: CE

Main Functions Realize protocol conversion and data transmission between IED internal bus and external Ethernet network. Transmit real‑time measured values, protection alarms, time‑stamped event logs and disturbance recording data to upper SCADA / DCS monitoring system. Receive remote control, remote setting group switching commands issued by upper‑level system and forward to IED main processing unit. Support IEC 61850 standard communication protocol for substation automation system. Front‑panel LED indicators show link status, data transmission status and fault alarm for on‑site inspection. Hardware self‑diagnosis detects communication channel abnormality and internal circuit fault, upload fault status to IED main board. IED configuration and parameter setting are completed by ABB PCM600 engineering tool.

Installation Requirement Slot‑type plug‑in installation inside Relion 615‑series IED chassis. Ensure reliable cabinet protective grounding. After module replacement, confirm full part‑number 1MRS050729 matches original project configuration, download complete IED configuration file. Perform communication link test and signal interaction verification with upper monitoring system. Different communication card variants cannot be directly interchanged without firmware adaptation and configuration download. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Communication interface module for Relion 615‑series protection and control IEDs, widely used in power‑grid substations, thermal‑power plants and hydropower plants, applied for substation‑automation‑system maintenance and spare‑part replacement.

Key Features

1. Dedicated communication plug‑in card for Relion 615‑series IEDs, realizes high‑speed data interaction between protection relay and station‑level monitoring system.
2. Support mainstream substation‑automation communication protocol IEC 61850.
3. Optional optical‑fiber interface provides strong anti‑interference capability for harsh electromagnetic‑environment substations.
4. Front‑panel LED status indication, convenient for on‑site commissioning and fault location.
5. Compact slot‑mount structure, convenient for on‑site replacement and maintenance; strict full‑part‑number matching shall be followed during spare‑part replacement.
