HIRSCHMANN OZD PROFI 12M G12

Hirschmann OZD PROFI 12M G12 – Profibus Fiber Optic Repeater

Description

The Hirschmann OZD PROFI 12M G12 is a reliable industrial fiber optic repeater for Profibus networks. It is designed to convert Profibus signals from electrical (RS-485) to optical signals, allowing for transmission over long distances and providing complete galvanic isolation. This makes it ideal for use in environments with high levels of electromagnetic interference (EMI). With support for data rates up to 12 Mbaud, this device ensures high-speed and error-free communication in critical automation systems. The robust metal housing and DIN-rail mount make it suitable for harsh industrial conditions.

FAQ

What type of fiber optic cable is compatible with the OZD PROFI 12M G12?

This repeater is designed for use with multimode glass fiber optic cables, typically with core/cladding diameters of 50/125 micrometers or 62.5/125 micrometers.

What is the maximum transmission distance for this repeater?

The maximum network extension depends on the data rate and the quality of the fiber. As a general guide, it can achieve distances up to 2850 meters at a data rate of 1.5 Mbaud.

Can this device be used in a redundant ring topology?

Yes, the dual optical channels are specifically designed to allow for the creation of redundant Profibus optical rings, which significantly increases network availability by providing an alternate data path in case of a cable break.
