Uses a pulse via two addresses to independently switch two solenoids with one drive (switch, signal) or one solenoid with two drives (three-way switch, double crossing switch, signal with distant signal). The module is protected against short circuits. Switches and signals with an electromagnetic drive that are to be controlled digitally must be equipped with a switch or magnetic accessory decoder. Lamps, light signals or track sections that are to be switched on and off digitally are digitized using a switching decoder. Uhlenbrock magnetic accessories and switching decoders can be used in Märklin, Motorola and DCC digital systems. In Motorola operation, addresses 1 to 320 can be addressed with the Intellibox, and addresses 1 to 256 can be addressed with other control panels. In DCC operat.
