Twin-ring fiber-optic communication for established PROFIBUS installations.
Siemens 6GK1502-4AB10 is the PROFIBUS OLM/S4 optical link module from the second-generation OLM range. It converts the electrical PROFIBUS segment for fiber-optic transmission and supports a twin-ring network arrangement. Siemens documentation identifies a transmission range from 9.6 kbit/s to 1.5 Mbit/s for this generation. The module provides an electrical RS485 PROFIBUS connection through a Sub-D9 interface and an additional two-pin terminal connection. It is intended for established industrial communication architectures where optical transmission, longer segment reach, galvanic separation between network areas, or improved immunity to electromagnetic interference is required. Network planning should account for the installed OLM generation and existing segment configuration.
Condition, availability and warranty are Stockoems commercial terms.
Verify the complete part number, network topology, transmission rate, connector arrangement, fiber type, segment timing and peer OLM generation before replacement. Siemens documentation states that OLM Version 2 is not upward compatible with OLM Version 3. A migration or mixed-generation network therefore requires an engineering review rather than a like-for-like assumption.
It is a PROFIBUS OLM/S4 optical link module in the second-generation Siemens OLM product range.
Siemens ordering information identifies 6GK1502-4AB10 for a twin-ring arrangement.
The documented range for this OLM generation is 9.6 kbit/s to 1.5 Mbit/s, excluding 45.45 kbit/s.
No direct equivalence should be assumed. Siemens documents OLM Version 2 as not upward compatible with Version 3.
Check the full suffix, installed OLM generation, ring design, interfaces, transmission rate and network timing.

After-sales response
Our workflow connects incoming inspection, label comparison, compatibility discussion, protective packing, shipment coordination and document preparation. Availability and dispatch timing are checked for each request; no unverified stock quantity or delivery date is promised. Written commercial terms support clear communication before shipment, while the after-sales channel records questions, return authorization requirements and agreed next steps.
Check whether the supplier records the complete part number, suffix, condition, label evidence, warranty terms and shipping documents in writing before payment.
Request product and label photos, a condition statement, compatibility-review scope, packing method, traceable shipment plan and return authorization process.
Risk signals include incomplete suffixes, substituted models without approval, reused label photos, unsupported technical claims, unclear warranty wording and pressure to accept an unverified delivery date.
