When configuring as a block signal, the module reacts automatically to the transmitted route state. This function requires tracks with permanent contacts, such as an isolated track side of Märklin tracks or with the 5206 track detector, two-wire track sections monitored. Up to two monitored sections are necessary per signal section. In this operating mode, the module automatically switches on 'drive' when the following section is reported as 'free' via the signal bus. If one of the two sections is occupied, the module switches to 'stop'. With the infectious tensile influence relay Kat.-No. 5228 the module can automatically stop the trains. This can be done either by switching off the driving current before the signal or even more exemplary in the case of digital systems by switching to th.
