Ruggedness family of RMC media converters is designed to bridge the gap between different types of network segments, speeds, and protocols. This reduces installation and configuration costs.

The RUGGEDCOM RMC20 is a utility-grade, protocol-independent, serial-to-fiber, and serial standards converter for all your serial communication requirements. Among its numerous functions, the RMC20 allows RS485, RS422, or RS232 devices or networks to communicate over secure, noise immune, optically isolated, fiber optic cabling at extended distances as well as convert RS232 to either RS485 or RS422 serial standards.

The RMC20 is also specifically designed to provide years of maintenance-free operation for all your mission-critical, real-time control applications.

You can place an order for the SIEMENS RUGGEDCOM RMC20 Serial to Fiber Converter online via one of our Middle East branches (Dubai/ Oman/Saudi Arabia) and get it delivered at a low cost at a specific time.
