The RBM is a universal, analog and digital track occupancy detector with an integrated feedback unit (LocoNet, XpressNet or S88). The RBM supports all digital formats and systems. In addition to the 4-channel 10A occupancy alarm unit, the module has 4 additional contact inputs available for free use (e.g. for the use of reed switches, contacts or another BM). The current sensitivity can be adjusted as desired in 255 fine steps. Therefore, the module is also ideal for large railway areas and can be used in damp conditions. It is also possible to configure the 4 inputs and thus various. To be able to switch switching tasks such as direction or level dependencies. Of course, a BM module can also be connected to this. XpressNet feedback is only possible at our headquarters! 8 LEDs for display.
