Märklin 60882 S88 DC Feedback Module Decoder, 16 Inputs, Green/White

On a busy Märklin Digital layout, the 60882 S88 DC feedback module reports which track sections are occupied. It connects to the S88 bus of a Central Station or Mobile Station, reading 16 isolated track sections or contact tracks through optocoupler inputs. The module is powered directly from the S88 bus, so no separate supply is needed, and its green and white housing fits neatly under the layout. It is suitable for modellers aged 15 and over who want automated block control or occupancy display.

Key specifications

• Feedback module for Märklin Digital systems
• S88 bus protocol, 6-pin ribbon cable connection
• 16 inputs for DC track sections, contact tracks or switch contacts
• Optocoupler isolated inputs
• Powered via S88 bus
• Colour: green, white
• Recommended age: 15+ years

Why choose it

The module expands feedback capability without an extra power supply. Its S88 interface works with existing Märklin control units, and the optocouplers protect the digital system from track wiring faults. It is a straightforward way to add occupancy detection for automated routes or signal interlocking.

Ideal use cases

• Block occupancy detection for train automation
• Monitoring hidden staging yards
• Triggering signals or level crossing logic
• Feedback for computer control software

Good to know

The module is not a locomotive decoder; it only provides feedback to the digital system. It connects in a chain with other S88 modules using the ribbon cable, and each module adds 16 inputs. The housing is compact and can be mounted under the baseboard.
