RMC 40

Product Description


The RMC40 is a 4-port unmanaged Ethernet switch that provides both copper-to-fiber media conversion as well as 10Mbps to 100Mbps speed conversion. Specifically designed to operate reliably in electrically and climatically harsh environments it is well suited for use in mission critical Ethernet networking applications.

The RMC40 is packaged in a compact, galvanized steel enclosure that allows either DIN or panel mounting for efficient use of cabinet space. It has an integrated power supply with a wide range of voltages for worldwide operability. An operating temperature range of -40 to +85°C (-40 to +185°F) without the use of internal cooling fans allows it to be placed in almost any location. It is compliant with EMI and environmental standards for utility substations, industrial plants, and intelligent transportation systems.
