HIRSCHMANN FIBEROPTIC MODULE FIP P/N: OZDFIPG3T

HIRSCHMANN FIBEROPTIC MODULE FIP P/N: OZDFIPG3 T

Hirschmann OZD FIP G3 T (Part Number: 933 847-521) is a high-performance industrial interface converter and repeater designed to bridge the gap between electrical and optical communication channels within WorldFIP and FIP fieldbus networks.

Engineered under the premium Belden Hirschmann line, this fiber optic module converts electrical RS-485 signals into optical signals, allowing seamless, immune, and long-distance field communications on challenging plant floors.

Featuring built-in signal regeneration (repeater function) and an integrated bus termination mechanism, the OZD FIP G3 T acts as a robust network pillar.

It safeguards critical industrial control loops against electromagnetic interference (EMI), voltage spikes, and ground loops while extending the spatial reach of classic FIP architecture.

Unique Product Description

The Belden Hirschmann OZD FIP G3 T is a rugged fieldbus repeater that translates conventional copper-wired FIP/WorldFIP bus segments into dual-channel optical lines.

Outfitted with one electrical Sub-D 9-pin port and two independent optical channels utilizing 4 x BFOC 2.5 (ST) socket connections, this module enables the construction of highly reliable linear, star, or redundant optical ring topologies.

Designed strictly for demanding industrial environments, the module is enclosed in a heavy-duty, fanless housing that easily snaps onto standard DIN rails.

It supports reliable data transmission rates up to 1 Mbit/s over quartz glass or PCF (HCS) fibers. 

With an integrated 150 Ohm bus terminator and dual-stage redundant power inputs (24V DC / 48V DC), the OZD FIP G3 T guarantees consistent signal propagation across vast, high-voltage, or explosive industrial sectors without data attenuation.

Product Advantages and Features

Complete Galvanic Isolation: By transitioning copper fieldbus cables to optical fiber, the module effectively eliminates cross-talk, heavy electromagnetic interference (EMI), and destructive ground loop currents.

Dual Optical Channels for Redundancy: Equipped with 2 optical channels (4 ports total), the module supports redundant ring networks, ensuring zero downtime if a fiber optic link breaks.

Low Transmission Latency: Operates with a ultra-low signal propagation delay of less than 1 microsecond ($lt 1text{ }mutext{s}$), making it ideal for deterministic, real-time control applications.

Integrated Termination Switch: Features a built-in 150-ohm bus terminator, removing the need for external termination resistors on electrical drops and simplifying fieldbus balancing.

Robust Redundant Power Management: Accommodates variable power supplies across 24V or 48V DC buses, providing uninterrupted network traffic if a single power plant grid goes dark.

Application Cases

Chemical and Petrochemical Refineries: Protects WorldFIP control lines routing through toxic or volatile processing zones where spark prevention and absolute EMI insulation are safety mandates.

Power Plants and Substation Control: Deployed alongside large transformers and high-voltage transmission lines where traditional copper communication paths suffer fatal signal corruption from magnetic fields.

Wastewater and Municipal Infrastructure: Connects highly decentralized pump blocks or remote PLC nodes across miles of outdoor territory via quartz glass fiber loops, offering implicit protection against lightning surges.

Installation and Maintenance

Installation Procedures

DIN Rail Fitting: Snap the rear bracket of the OZD FIP G3 T securely onto a standard 35 mm DIN rail. Ensure it locks firmly into place to avoid vibration displacement.

Electrical Bus Hookup: Secure the electrical segment by plugging the 9-pin Sub-D connector into the electrical port, adhering to the NF-C 46-604 pinout standard.

Termination Configuration: If this unit represents the physical endpoint of the copper line segment, toggle the integrated bus terminator switch to ON (150 Ohm active).

Fiber Optics Termination: Remove the protective dust boots from the BFOC 2.5 sockets. Carefully twist and
