Märklin 60881 Módulo de retorno digital s88 para 16 entradas de contacto – Verde/Branco

The Märklin 60881 s88 decoder stands apart from conventional occupancy detectors by delivering 16 galvanically isolated feedback inputs in a compact, daisy-chainable module. Instead of relying on complex bus addresses or proprietary wiring, it uses the proven s88 feedback bus to report track occupancy and switch positions directly to your Märklin Central Station, Control Unit, or Interface. This makes it an ideal building block for automated block control, hidden staging yards, and signal interlocking on medium to large layouts.

Highlights

• 16 independent feedback inputs for contact tracks, reed switches, or current sensors
• Standard s88 bus interface with input and output connectors for easy daisy-chaining
• Compatible with Märklin Digital systems supporting s88 (Central Station, Control Unit, Interface)
• Robust plastic housing in green and white, designed for fixed installation under the layout
• No separate power supply needed – powered directly via the s88 bus

In daily use

Install the 60881 close to the track sections you want to monitor, then connect up to 16 occupancy detectors or reed contacts to the screw terminals. The module immediately forwards any change of state to the digital command station over the s88 bus. Because multiple modules can be linked in series, you can expand feedback coverage incrementally without rewiring the entire layout. The clear colour coding and labelled terminals simplify troubleshooting, while the durable housing protects the electronics from dust and accidental contact.
