OLM/P11 V4.1 module with one RS-485 interface and one plastic-fiber interface using two BFOC sockets.
The Siemens 6GK1503-2CA01 is a PROFIBUS OLM/P11 V4.1 optical link module supplied as a spare part. It connects one electrical RS-485 PROFIBUS interface with one plastic-fiber interface implemented by two BFOC sockets. The module supports PROFIBUS data rates from 9.6 kbit/s to 12 Mbit/s and includes a signaling contact plus a measuring output. Correct replacement requires confirmation of the fiber type, connector format, link length, supply voltage and installed network topology.

Link an RS-485 PROFIBUS segment to a plastic-fiber path using the specified BFOC optical interface.
Extend or separate PROFIBUS sections where fiber helps address distance, isolation or interference considerations.
Replace an OLM/P11 V4.1 only after verifying the exact article number, connector type, fiber medium and network rate.
Siemens has issued a product phase-out declaration for PROFIBUS OLM Pxx V4.1 devices and the current lifecycle stage is Product Cancellation. Availability and condition must be confirmed for the exact article number 6GK1503-2CA01.
It is a PROFIBUS OLM/P11 V4.1 optical link module with one RS-485 interface and one plastic-fiber interface.
The plastic-fiber interface uses two BFOC sockets.
The official data range is 9.6 kbit/s to 12 Mbit/s; PROFIBUS PA is listed at 45.45 kbit/s.
Siemens lists up to 400 m for the stated PCF cable and up to 80 m for the stated POF cable under the specified attenuation conditions.
Confirm P11 V4.1, fiber medium, BFOC connectors, link length, RS-485 topology, transmission rate and 24 V DC supply.
Send the exact article number, quantity, condition requirement, destination and application details. We will check availability, compatibility points, worldwide delivery options and warranty terms.
Our service focuses on exact-code verification, condition transparency and practical compatibility checks for industrial automation parts. For this PROFIBUS OLM/P11 V4.1, the optical medium, BFOC connections and RS-485 network details are checked with the complete code before an offer is prepared.
A sales coordinator checks the full article number, quantity, destination, delivery priority and documentation needs. This reduces the risk of a quotation based on a shortened Siemens code or an incorrect hardware variant.
The request is compared with verified manufacturer data. For 6GK1503-2CA01, key checks include the P11 V4.1 identity, one RS-485 interface, two BFOC sockets, supported fiber type, link length and 18-32 V DC supply.
Packaging, export documentation and shipping options are coordinated according to the destination and urgency. The offer states the supplied condition, lead-time basis and warranty terms for stakeholder review.
We retain the complete code 6GK1503-2CA01 throughout the inquiry. Nameplate photos, packaging labels and available documentation can be cross-checked so the requested variant is not confused with a related family member.
Compatibility is assessed from the PROFIBUS rate, RS-485 topology, POF or PCF cable data, BFOC connector condition, measured link length, supply voltage and diagnostic-contact requirements.
Where available, visual evidence can be requested for the label, housing, terminals, interfaces and package contents. Condition, lead time, delivery method and warranty coverage are clarified in the quotation.
| Request item | Why it matters |
