SCALANCE X accessories, media module MM992-2VD, 2x 10/100/1000 Mbit/s RJ45 ports, electrical, with retaining collar, variable distance, . SCALANCEMM992-2VD (RJ45, variable distance)With the media module (variable distance), which is plugged into a modular Layer 2 switch or a security module, any two-wire cable can be used for Ethernet connections up to 1000 m: e.g. underground cables, cables through firewalls or along pipelines, which are difficult to replace. This also makes it possible to set up PROFINET connections of up to 300 m. Unlimited flexibility for network extensions (e.g. more end devices) or conversions (e.g. switching from copper to fiber optic) thanks to modular design with media modules. Reduction of storage costs and maintenance effort by focusing on a few basic device variants.
