Optical link module for PROFIBUS in harsh environments
The Siemens 6AG1503-2CC00-2AA0 is a SIPLUS NET OLM/G11-1300 V4.0 — an active optical link module that bridges one RS-485 segment to one glass fiber optic interface (BFOC) running at 1300 nm. It is the ruggedized version of the standard 6GK1503-2CC00, with conformal coating and an extended temperature range of -25 to +60 °C, making it suited for applications with airborne contaminants, cooling lubricants, and diesel or oil droplets. Powered by a 24 V DC supply (18.8 to 28.8 V range), it draws 0.2 A maximum, which keeps the panel power budget tight. The module supports PROFIBUS DP at data rates from 9.6 kbps up to 12 Mbps, and also handles PROFIBUS PA at 45.45 kbps via the same RS-485 port.
Lifecycle and sourcing posture
This part is listed as active by Siemens — no end-of-life notice or last-time-buy constraints. For a procurement team evaluating BOM stability, that means standard lead times apply and no near-term obsolescence risk. Conformal coating variants like this one are typically built to order in smaller batches, so quoted lead times may run slightly longer than the base module; plan accordingly for line-down replacement or new-build project windows.
