Description
1. Product Title
ABB 1MRK002311‑AA‑ Medium‑Range Optical Line Data Communication Module
2. Product Overview
The 1MRK002311‑AA is an optical line data communication module manufactured by ABB, developed for reliable long‑distance signal transmission within Relion series protection and control IED systems. This hardware converts electrical data signals into optical signals for single‑mode fiber transmission, eliminating electromagnetic interference induced by high‑voltage substation environments. 1MRK002311‑AA establishes stable communication links between protection relays across different bays or remote substations. It mitigates signal distortion, ground loop noise and data dropout risks that frequently occur with copper‑based cabling, maintaining consistent data throughput for critical power‑system protection logic execution.
