Why the 1MRK002266-AAr00 Matters
When a optical ethernet module fails in a ABB system, the consequences range from nuisance alarms to complete process shutdown. The ABB | 1MRK002266-AAr00 | Optical Ethernet Module is not a generic part you can substitute — it is engineered for a specific slot in a specific chassis with specific firmware requirements.
ABB's industrial automation portfolio spans DCS, PLC, and power electronics. This module integrates into ABB Ability System 800xA, Advant OCS, or AC 800M platforms depending on the specific series.
Here is what defines this particular module: Model: 1MRK002266‑AAr00
Type: Optical Ethernet Module
Series: Relion® protection and control systems
Function: Fiber‑optic Ethernet communication for relays and IEDs.
We stock this unit in our Shenzhen warehouse — physically, not as a virtual listing. Each one is powered up and tested before shipping, with a 48-hour burn-in at elevated temperature. If you are maintaining a ABB system with no spare modules on the shelf, we strongly recommend ordering at least one backup. The cost of the spare is negligible compared to the cost of emergency sourcing during a plant trip. 12-month warranty, ships within 24 hours.
