The Wacker Neuson Relay is a genuine OEM component designed for the RC50, RC70, RC110, and RD Series single drum soil compactors and vibration rollers. As a factory-sourced part, it is built to the exact electrical specifications of the original, ensuring correct switching behavior and seamless integration with the machine's control system. This relay is confirmed to fit an extensive range of RC and RD Series configurations including CAB, ROPS, DPF, and electric-drive variants, making it the dependable choice when an exact replacement is required.
Key Features
- Exact OEM Electrical Rating — Sourced directly from Wacker Neuson, this relay matches the original coil voltage, contact load rating, and switching characteristics required by the machine's electrical system.
- Drop-In Connector Compatibility — Designed to plug directly into the existing wiring harness socket without modification, preserving the integrity of the circuit layout.
- Broad RC and RD Series Coverage — Fits RC50, RC50p, RC70, RC70p, RC70vo, RC110, RC110p, RD24e-100, and RD28e-120 variants across CAB, ROPS, DPF, and electric-drive configurations.
- Protects Critical Machine Functions — A correctly functioning relay ensures that high-current circuits — such as those controlling the drum vibration, engine start, or auxiliary systems — switch cleanly and consistently under load.
- Electrical Safety Assurance — A degraded or failed relay can cause intermittent operation, circuit arcing, or uncontrolled activation of powered systems; replacing with the correct OEM part restores predictable, safe circuit control.
A relay is an electrically operated switch that allows a low-power control signal to open or close a high-current circuit safely. In soil compactors and vibration rollers, relays are used throughout the machine's electrical system to manage functions such as engine starting, vibration engagement, and auxiliary power distribution. When a relay fails, the circuit it controls may stop responding, behave intermittently, or in some cases remain energized when it should not — any of which can halt operation or create unsafe conditions on the worksite.
