The DIN-rail mountable 500NMD20 is a managed plug and play layer-2 switch providing four Fast Ethernet auto-negotiating RJ45-ports with auto MDI/X (Automatic Crossover Detection and Correction) and two SFP (small form-factor pluggable) module slots for use with fibre optictransceivers. Depending on the SFP module equipped, the unit is able to span distances by fibre optic cable up to 40 km (or even more with special SFP modules). The switch is able to provide redundant topologies by the
The ABB 500NMD20 is a managed plug-and-play Layer 2 switch designed for DIN-rail mounting. It provides four auto-negotiating Fast Ethernet RJ45 ports with Auto MDI/X support and two SFP module slots for fiber optic transceivers, enabling transmission distances up to 40 km depending on the module used.
