Description
1. Product Title
ABB 1MRK002122‑AB‑ Multi‑Mode Optical Line Data Communication Module
2. Product Overview
The 1MRK002122‑AB is a plug‑in optical communication module built for ABB Relion series protection and control IEDs in substation automation systems. This unit converts electrical logic signals to multi‑mode optical signals, delivering galvanically isolated data transmission between bay‑level protection relays. 1MRK002122‑AB suppresses electromagnetic interference generated by high‑voltage switchgear environments, avoiding ground‑loop noise and data corruption on copper wiring. It supports stable short‑range fiber‑based inter‑relay communication required for line differential protection schemes. This module mitigates intermittent communication drop‑outs and helps maintain the integrity of protection logic execution in harsh utility operating conditions.
