The LoDi-RM-16+ is a versatile feedback module for the S88.2 and s88 bus systems, optimized for 3-rail systems but also suitable for push buttons, hall sensors, reed switches, light barriers, and more. Thanks to the integrated diode trick, ground is fed back in 3-rail operation, significantly improving locomotive reliability within the feedback section. The address is stored directly in the module, allowing it to be repositioned freely within the bus without requiring changes in the model railway software. Easy configuration via LoDi-ProgrammerFX and convenient monitoring through the display.
The LoDi-RM-16+ is a smart feedback module for digital model railway systems, specially designed for the 3-rail system but also universally applicable for other feedback tasks. Whether you're using push buttons, reed switches, Hall sensors, light barriers, or turnout feedback, this module is flexible, robust, and future-proof.
✅ 16 feedback inputs per module
✅ Optimized for 3-rail systems with integrated diode trick
✅ Also ideal for push buttons, reed switches, light sensors & limit switches
✅ Fixed S88.2 address stored in the module – freely movable on the bus
✅ Input labeling supported (depending on model railway software)
✅ Display screen for checking input states and module address
✅ Compatible with S88.2, S88N, and legacy S88 via adapter
✅ Easy configuration via LoDi ProgrammerFX
The LoDi-RM-16+ automatically returns the ground signal on the feedback side, which leads to more stable locomotive power supply within detection sections of 3-rail systems (e.g., Märklin). No external diodes or additional modules are required.
In the past, wiring changes often caused address shifts. Thanks to the internally stored module address, those problems are eliminated—the module can be moved anywhere in the S88.2 bus chain without having to reconfigure your software.
