What to Confirm Before Ordering Hirschmann OZD Profi 12M G22 EEC for an Industrial Network Project
Confirm the full ordering identity
Hirschmann OZD Profi 12M G22 EEC identifies the Hirschmann PROFIBUS electrical-to-optical repeater, model OZD Profi 12M G22 EEC, part number 942148103. 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) 2 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 860 nm multimode 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, -25 to +60 °C °C, and dimensions of 39.5 x 137.5 x 84 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 G22 EEC with part number 942148103, 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.
Replacement decision note
Port count or appearance alone does not establish replacement compatibility. Compare exact identity, interfaces, supply, mechanics, environmental limits and approvals together. Where an installed unit is involved, capture its settings and wiring before removal and document the reason for replacement.
