Description Reviews

Description

The Siemens 6GK1503-2CB00 is a SIMATIC NET PROFIBUS OLM/G11 (Optical Link Module) version 4.0, designed for converting PROFIBUS electrical signals into optical signals for transmission over fiber-optic cables. This module enables robust, interference-free communication in industrial environments, particularly where electromagnetic compatibility (EMC) or long-distance transmission is required.

Features

Supports PROFIBUS data transmission rates from 9.6 kbit/s up to 12 Mbit/s.
Equipped with one RS485 interface for electrical connection and one glass fiber-optic interface featuring two BFOC sockets.
Includes an integrated signaling contact for diagnostic monitoring and a dedicated test port for maintenance.
Designed for 24 V DC supply voltage with a wide operating range of 18.8 V to 28.8 V.
Integrated fusing at the power supply input for enhanced operational safety.

Applications

The OLM/G11 is widely used in industrial automation networks, including manufacturing plants, water treatment facilities, and power distribution systems, to extend the reach of PROFIBUS segments and provide galvanic isolation between network nodes.

Installation Guidelines

Ensure the module is mounted in an environment free from excessive dust, moisture, and corrosive gases.
Use shielded twisted-pair cables for the RS485 connection to minimize electromagnetic interference.
When handling fiber-optic cables, ensure the connectors are clean and free of dust before insertion into the BFOC sockets.
Always power down the system before connecting or disconnecting the power supply or communication cables.
Ensure proper grounding of the module chassis to the system ground to maintain signal integrity.

FAQ

What is the primary function of the OLM/G11?

The OLM/G11 acts as a bridge between electrical PROFIBUS segments and fiber-optic segments, allowing for longer cable runs and immunity to electromagnetic interference.

Is this module compatible with all PROFIBUS baud rates?

Yes, the V4.0 module supports all standard PROFIBUS baud rates ranging from 9.6 kbit/s up to 12 Mbit/s.
