The BD4N DCC 4 Block Occupancy Detector from Digitrax provides cost-effective occupancy detection for four sections. Unit features 8A capacity suitable for all scales, outputs for panel-mounted LEDs (sold separately) to display occupancy. It will detect any powered loco, and unpowered rolling stock equipped with resistor wheelsets using its adjustable resistance-current detection section (DS) trip threshold. The unit features on-board status LEDs for stand-alone occupancy and track power indication, expandable for optional LT5 or fascia mounted occupancy indicator LEDs. Requires DS64 or SE8, both sold separately, to transmit occupancy information to the LocoNet System. The BD4N DCC 4 Block Occupancy Detector is a replacement for the BD4. Show more
