Convertor industrial RS232 ROLINE 21.13.1141

The ROLINE Industrial Converter RS232 to Multimode Optical Fiber (model 21.13.1141) provides a reliable link between two RS-232 serial devices using multimode fiber with SC connectors. It performs transparent conversion of RS-232 data and all control signals, supports all baud rates without user configuration, and is designed for installation in industrial cabinets with a DIN-rail mountable metal housing. The unit offers enhanced signal protection and is rated for wide operating temperature and power ranges to suit industrial environments.

Advantages

The converter ensures full transparency for RS-232 lines and control signals, eliminating the need for protocol or baud-rate adjustments. It includes surge, ESD and isolation protection for RS-232 interfaces, supports a wide input voltage range (7–30 V DC), and features fanless rugged metal housing with DIN-rail mounting for industrial use. The device provides industrial-rated emission and immunity performance and operates across a wide temperature range.

Suitable for

• Extending RS-232 connections over long distances using multimode fiber
• Industrial automation cabinets and control enclosures
• Environments requiring electromagnetic interference protection and signal isolation
• Applications where plug-and-play RS-232 conversion and compatibility with any baud rate are needed

How to use

Mount the converter on a DIN-rail inside the cabinet and connect the RS-232 serial devices to the RS-232 interface. Connect the multimode fiber using SC connectors between the two converter units. Supply power via the terminal block or the DC plug (7–30 V DC). The device operates transparently without requiring baud rate or protocol settings; once powered and connected, it forwards RS-232 data and control signals over the optical link.

Recommendations

Install the converters at both ends of the fiber link and use a suitable DIN-rail power supply (recommended ROLINE DIN-rail PSU 21.13.1226) to ensure stable operation. Verify fiber type and connector compatibility (multimode SC) and maintain proper grounding and isolation for best immunity performance.
