Hirschmann OZD PROFI 12M G12 Optical Fiber Repeater

Product Summary

The Hirschmann OZD PROFI 12M G12 (942148-002) is a high-performance industrial repeater designed to bridge the gap between electrical PROFIBUS DP networks and optical fiber segments. Featuring 3 ports (1 electrical and 2 optical), this unit allows for the creation of reliable, long-distance PROFIBUS networks that are completely immune to electromagnetic interference (EMI). With a maximum data rate of 12 Mb/s, it is the industry standard for ensuring high-speed data integrity in harsh industrial environments.

Core Performance Features

• Fiber Optic Redundancy: Equipped with two optical ports, the G12 model supports redundant ring topologies, ensuring that the network remains active even if one fiber link is severed.

• Maximum PROFIBUS Speeds: Supports the full range of PROFIBUS DP transmission speeds up to 12 Mb/s, with automatic baud rate detection.

• Electrical-to-Optical Conversion: Seamlessly converts RS-485 electrical signals to glass fiber (multimode), extending the network range significantly beyond the limits of copper cabling.

• Industrial Durability: Built to operate in demanding conditions with a wide supply voltage range (18V to 32V DC) and an operating temperature range of 0°C to +60°C.

• Failure Signaling: Includes an integrated signaling contact for reporting link failures or power loss to a central control system.
