The Wacker Neuson Relay is a genuine OEM Relay designed for the RD24e-100, RD28e-120, and RC110 series tandem drum rollers. As a factory-sourced component, it meets the exact electrical specifications of the original part, ensuring proper circuit control across all covered models. This relay is compatible with ROPS and CAB variants of the RC110 and RC110p, as well as the standard, cab, and offset drum configurations of the RD24e-100 and RD28e-120 series. Sourcing a direct OEM replacement like the is the surest way to restore correct electrical function and avoid recurring issues caused by an out-of-spec substitute.
Key Features
- Matched Electrical Specification — Meets the coil voltage and contact rating of the original relay, ensuring proper switching behavior in the machine's electrical system.
- Direct OEM Replacement — Drops into the original relay socket with no adaptation needed, preserving the integrity of the wiring harness and connector.
- Broad Series Compatibility — Fits RD24e-100 and RD28e-120 series (standard, cab, and offset drum variants) plus RC110 and RC110p ROPS and CAB models.
- Correct Circuit Switching Restored — A failed relay can prevent critical systems from energizing or cause unintended activation; replacing it with the correct OEM part restores predictable, repeatable electrical control.
- Electrical Safety Compliance — Using the OEM-specified relay maintains the designed protection levels for the circuits it controls, an important consideration on compact roller electrical systems.
- Genuine Wacker Neuson Part — Supplied under part number 5100073112 direct from the Wacker Neuson OEM supply chain, so you know exactly what you're installing.
A relay is an electrically operated switch that uses a low-power control signal to open or close a higher-power circuit. On compact tandem rollers like the RD and RC series, relays manage power delivery to key operating systems — including propulsion controls, vibration circuits, and safety interlocks. When a relay fails, the circuit it controls may become permanently open (causing a system to stop working entirely) or permanently closed (causing unintended or unsafe operation), both of which can take a machine out of service until the fault is resolved.
