Siemens 6GK1503-2CB00 SIMATIC NET PROFIBUS OLM/G11 V4.0 Networking Accessory

The Siemens 6GK1503-2CB00 is a PROFIBUS OLM/G11 V4.0 optical link module that bridges one RS485 PROFIBUS segment to a glass fiber-optic segment through a single BFOC port, carrying 9.6 kbit/s to 12 Mbit/s (or 45.45 kbit/s for PROFIBUS PA). It runs on 24 V DC, includes a signaling contact and test port, and supports ring redundancy.

Selection Notes

The OLM/G11 designation identifies this as a single-channel glass fiber link (G) with one optical port; select it where a PROFIBUS segment needs exactly one fiber hop into an electrically isolated or long-distance section, rather than the multi-port OLM variants used to build fiber rings with several branches. The redundant power input and signaling contact let it report a supply or link fault to a separate monitoring circuit, which matters for segments running unattended. IP40 and 0-60 °C keep it inside a cabinet rather than a field enclosure.

Applications

PROFIBUS segments crossing high-EMI plant areas or distances beyond copper RS485 limits, and marine or offshore installations where the listed classification-society approvals (ABS, BV, DNV, GL, LRS, NK) apply.
