Siemens SIMATIC NET PROFIBUS Optical Link Module
Description
The Siemens 6GK1503-2CB00 is an OLM G11 V4.0, an Optical Link Module for PROFIBUS networks. It is designed to convert electrical PROFIBUS signals from an RS485 interface to optical signals for transmission over glass fiber optic cables. This enables communication over long distances (up to 2850m) and provides excellent immunity to electromagnetic interference, making it ideal for robust industrial applications.
