As a multi-protocol control unit, the Central Station 3 with its high-resolution, modern colour touch screen, the 2 speed controllers as well as the integrated central track diagram control panel offers the possibility for simple and comfortable control of the locomotives and the entire layout. For locomotives, up to 32 functions can be switched, for accessories, up to 320 Motorola or 2048 DCC solenoids are possible. Furthermore, the Central Station 3 has 2 built-in locomotive card readers (for storing locomotive data on a locomotive card or for quickly calling up the locomotive by inserting the locomotive card), an SD card slot for memory expansion as well as an integrated loudspeaker for playing sounds typical for model railways. A powerful booster is integrated to supply the layout with traction and switching current. Additional driving consoles, further layouts and keyboards extend the operation of the layout, whereby common and separate configurations for the layout areas to be controlled can be kept in the Central Station 3 (plus). The Central Station 3 has 2 built-in USB hosts (for e.g. mouse, keyboard, USB stick), a USB charging socket, a network connection for communication with a PC, connections for 2 Mobile Stations, a connection for external loudspeakers and others for the Märklin bus system. S88 connections can be realised externally by means of Link s88 (60883). Load capacity at the connecting track: max. 5 A, load capacity at the programming track: max. 1.2 A.
