HIRSCHMANN OZD PROFI 12M G11 943 727-221

Hirschmann OZD PROFI 12M G11 Fiber Optic Repeater Description The Hirschmann OZD PROFI 12M G11 is a robust fiber optic module designed to extend and enhance the reliability of Profibus networks. By converting electrical Profibus signals into optical signals, it allows for communication over much longer distances than copper cable and provides complete electrical isolation, making it immune to electromagnetic interference (EMI). This module is ideal for use in harsh industrial environments and for creating complex network topologies such as line, star, or redundant rings.

Specifications Manufacturer: Hirschmann (A Belden Brand) Model: OZD PROFI 12M G11 Part Number: 943 727-221 Network Protocol: Profibus DP Data Rate: 9.6 kbps to 12 Mbps (automatic detection) Power Supply: 24V DC Fiber Optic Ports: 2x ST Sockets (Multi-mode) Electrical Port: 1x D-Sub 9 (DB9) Socket Operating Temperature: 0 deg C to +60 deg C Mounting: DIN Rail Label Info Certifications: UL, FM, CE, FCC Class B ATEX Rating: II 3G EEx nC [L] IIC T5 Year of Manufacture: 2003 Application This module is perfectly suited for process automation, manufacturing plants, and any application requiring a reliable and long-distance Profibus connection, especially in environments with high levels of electrical noise. Country of Origin Made in Germany CO2 Impact By purchasing this pre-owned module, you help avoid the production of a new one, saving an estimated 20 kg of CO2. This is comparable to the emissions from a 100 km car journey. Availability This is an obsolete item, but it is available from our stock for immediate dispatch. Essential for maintaining and repairing existing legacy systems. FAQ What type of fiber optic cable and connectors are required for the OZD PROFI 12M G11?This module uses multi-mode fiber optic cable. The connectors on the device are ST (Straight Tip) type, which is a common bayonet-style fiber optic connector. What is the maximum distance this fiber optic module can cover?The maximum distance between two OZD Profi modules depends on the fiber type and quality, but for standard multi-mode fiber (e.g., 62.5/125 um), it can typically bridge distances up to 3000 meters (3 km). How do I configure the network topology (line, star, ring) on this device?The network topology is configured using the DIL switches on the side of the unit, as indicated on the label. DIL switches S1, S2, S3, and S4 are used to set the mode for the channels, allowing you to configure line, star, or redundant ring topologies.
