Product Overview

M2LR‑00‑000‑0 is redundancy link module for GE MasterLogic‑200 PLC. It establishes high‑speed synchronization communication between primary and standby CPU modules, realizing bumpless hot‑standby switch‑over for high‑availability control applications. It continuously monitors redundancy link status and triggers fault alarms when synchronization failure occurs. End‑of‑production module is supplied as refurbished and new‑old‑stock spare parts for critical‑process‑automation system maintenance.

Application Notes

‑ Must be deployed in pairs for dual‑CPU redundant configuration. ‑ Use dedicated redundancy cable according to hardware manual specifications. ‑ ESD precautions must be observed during module replacement. ‑ Typical deployment: oil‑gas processing, power‑plant auxiliary control spare‑part stocking.
