The Wacker Neuson Relay is a genuine OEM relay designed for the RC and RD series compactors and tandem rollers, including the RC50, RC70, RC110, RD40-130, RD45-140, and RD24-100 families. As a factory-sourced component, this relay is built to the exact electrical specifications required by these machines, ensuring proper circuit control and switching performance. It covers an extensive range of configurations — including CAB, ROPS, DPF, and VO variants — making it the correct choice across a wide breadth of Wacker Neuson soil and asphalt compaction equipment.
Key Features
- Exact Electrical Specification: — Manufactured to OEM switching ratings and coil resistance values, so the relay operates within the designed current load of your machine's electrical system.
- Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson, this relay carries the same part number — 5100023231 — used by authorized dealers and service centers worldwide.
- Broad Compactor Compatibility: — Fits RC50, RC50p, RC70, RC70p, RC70vo, RC110, RC110p, RD24-100, RD28-120, RD40-130, and RD45-140 series machines across standard, DPF, CAB, and ROPS configurations.
- Direct Drop-In Replacement: — Matches the OEM connector and mounting footprint, allowing straightforward installation without wiring adaptation or bracket modification.
- Electrical Circuit Protection: — A properly functioning relay isolates high-current loads from control circuits, preventing switch burnout and protecting sensitive control components from damage caused by a failed or arcing relay.
- Correct Switching Ensures Safe Machine Operation: — On compaction equipment, relays govern critical functions including ignition and auxiliary systems; installing the correct OEM-rated component maintains intended circuit behavior and prevents unintended electrical faults.
A relay is an electrically operated switch that allows a low-power control signal — such as a switch or controller output — to activate a high-current circuit, like a starter motor, fuel system, or auxiliary load. On Wacker Neuson compactors and tandem rollers, relays are integrated throughout the machine's electrical architecture to manage switching of key operating circuits safely and reliably. When a relay fails — through contact wear, coil burnout, or internal arcing — the circuit it controls may stop functioning entirely or behave erratically, leading to starting issues, loss of machine function, or potential electrical damage downstream.
