Siemens 6GK1503-3CA00 is a PROFIBUS OLM/P12 V4.0 optical link module. It combines an RS-485 interface with two plastic-fiber optical channels. The optical connections use BFOC sockets. A signaling contact and test connection assist network supervision. The module requires an external DC supply.
The 6GK1503-3CA00 links compatible electrical and optical PROFIBUS segments. Optical transmission supports network layouts that require separation from electrical interference. The two optical channels can form part of the selected line or redundant-ring arrangement. Fiber type and attenuation must suit the intended link. This V4.0 catalog number must be distinguished from the later V4.1 version.
Connects an electrical PROFIBUS segment with compatible plastic-fiber links.
Supports the configured line or redundant optical-ring arrangement.
Provides a signaling contact and measurement access for maintaining the optical installation.
No. This catalog number is OLM/P12 V4.0; verify the full order number for replacement.
Do not assume compatibility. This P12 configuration uses the specified plastic/PCF optical media.
Confirm fiber type, link attenuation, operating mode and the ring configuration.
It includes a signaling contact and a test connection for the supported supervision functions.
Ask Jim for actual-item photographs, the stated condition and available inspection details. The quoted warranty is 12 months under the agreed terms.
Confirmed in-stock goods are dispatched immediately after payment is received. Courier and tracking information are supplied after shipment.
Germany – A Germany customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.
India – An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.
Malaysia – A Malaysia customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
