Mitsubishi QJ72LP25GE — GI Fiber Link Module for Remote I/O
The Mitsubishi QJ72LP25GE is a GI (Graded Index) fiber optic link module for the Melsec Q-series PLC platform. It serves as the remote station communication interface, linking remote I/O racks back to the main CPU via a fiber optic ring or bus topology.
The QJ72LP25GE carries a mature lifecycle status. It is not in current factory production, so new-stock availability is limited to surplus and distributor inventory. For a like-for-like replacement, the buyer should verify the fiber type (GI) and the remote-station protocol against the existing Melsec Q-series network configuration.
