The RUGGEDCOM RMC20 series of media converters are industrially hardened
and specifically designed to operate reliably in electrically harsh and climatically
demanding environments.
The RUGGEDCOM RMC20 is a utility-grade, protocol-independent, serial-to-fiber
and serial standards converter for all your serial communication requirements.
The RUGGEDCOM 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 convert RS232 to either RS485 or RS422 serial standards.
The RUGGEDCOM RMC20 was designed specifically to provide years of maintenance
free operation for all your mission-critical, real-time control applications. To provide
the utmost in reliability, the RUGGEDCOM RMC20 is tested to the most stringent
international EMI and environmental standards for use in HV/MV electric utility
substations and industrial manufacturing, process and control and intelligent
transportation systems applications. All RUGGEDCOM products are packaged with a
high reliability, built-in power supply (24V, 48V or HI voltage options) and enclosed
in a rugged galvanized steel enclosure suitable for panel or DIN-rail mounting.
