Planning an Industrial Application with Hirschmann OZD Profi 12M G12-1300 PRO and Its Verified Manufacturer Data
Confirm the full ordering identity
Hirschmann OZD Profi 12M G12-1300 PRO identifies the Hirschmann PROFIBUS electrical-to-optical repeater, model OZD Profi 12M G12-1300 PRO, part number 943906321. Keep the complete model and part number together in the RFQ because nearby family members may differ in interfaces, optical medium, environmental range, software, housing or supply arrangement.
Match the repeater topology
The exact interface statement is 2 x optical: 4 sockets BFOC 2.5 (STR); 1 x electrical: Sub-D 9-pin, female, pin assignment according to EN 50170 part 1. Count the required electrical PROFIBUS segments and optical channels, then choose a line, star or redundant arrangement supported by the project design. G11, G12, G22, P11, P12 and P22 suffixes are not interchangeable shorthand; they describe different connection resources.
Calculate the optical link
This model should be reviewed for 1310 nm long-distance fiber planning. Confirm fiber construction, wavelength, attenuation, connector type, splice loss and route length at both ends. Use the published link budget with an engineering reserve rather than treating the maximum catalog distance as a guaranteed result for every installed cable.

Check environment and mounting
The source lists 18 ... 32 VDC, typ. 24 VDC, 0 to +60 °C °C, and dimensions of 35 x 163 x 119 mm. Confirm whether the requested version is standard, EEC or PRO and compare its protection and mounting details. Cabinet temperature, power redundancy, grounding, clearance and hazardous-area documentation require project-specific review.
Preserve PROFIBUS commissioning data
Record baud rate, segment length, termination position, node layout and optical status results during commissioning. Keep label photographs and the accepted fiber schedule with the device record. These details help maintenance teams distinguish a fiber fault, electrical-bus issue or configuration problem when service is later required.
Request the exact OZD version
Quote Hirschmann OZD Profi 12M G12-1300 PRO with part number 943906321, quantity, destination and required delivery date. Include the existing or proposed topology, fiber type, route length and environmental conditions. Ask the supplier to identify included terminal blocks and any separately ordered fiber connectors, power equipment or mounting accessories.
Lifecycle documentation
Keep the quotation, manufacturer source, delivered-label photograph and final drawing in one lifecycle file. Clear records distinguish the approved configuration from nearby family variants and reduce delays when a future spare, accessory or compatible network component is requested.
Technical reference: manufacturer source for OZD Profi 12M G12-1300 PRO. Verify current documentation and the delivered revision before final engineering approval.
