The LoDi-8-GBM v2 is a powerful track occupancy detection module for both 2-rail and 3-rail systems, designed for the modern S88.2 bus. It monitors up to 8 track sections with up to 3 amps each, detects RailCom-enabled locomotives on Channels 1 & 2, and simultaneously measures power consumption per section. It also features built-in short-circuit detection with adjustable thresholds. With full DCC-A readiness, firmware update capability, and display compatibility, the LoDi-8-GBM v2 is ideal for all modern feedback requirements. Backward compatible with s88N.
The LoDi-8-GBM v2 is the second generation of our advanced track occupancy detector, designed for precise feedback on digital model railway layouts—from small modules to large-scale systems.
Thanks to its integration with the new S88.2 bus and expanded features, the LoDi-8-GBM v2 offers an unmatched level of detection quality—with RailCom, current sensing, short-circuit monitoring, and a clear display for real-time status feedback.
