The Wacker Neuson is a genuine OEM Relay Assembly designed for the RD27-100 and RD27-120 hydrostatic vibratory tandem rollers. Sourced directly from Wacker Neuson, this assembly meets the exact electrical specifications required by the RD27 platform. It is a direct, verified replacement for multiple machine configurations across both the RD27-100 and RD27-120 series, ensuring correct fitment without guesswork.
Key Features
- OEM-Matched Switching Specs — Built to the exact coil voltage and contact rating required by the RD27 electrical system, ensuring correct switching behavior across all controlled circuits.
- Drop-In Connector Compatibility — The 5000161583 plugs directly into the factory harness connector on RD27-100 and RD27-120 machines, with no wiring modifications needed.
- Broad RD27 Series Coverage — Confirmed fitment across RD27-100 and RD27-120 hydrostatic vibratory roller configurations, covering multiple serial number ranges within each model.
- Protects Critical Machine Functions — A failed relay can cause complete loss of control over key electrical circuits, including drive, vibration, or safety interlock systems. A correctly functioning relay restores full operational control.
- Electrical Safety Integrity — As a switching component in the machine's control circuit, a properly rated relay prevents overcurrent conditions from reaching sensitive downstream components, protecting both the operator and the electrical system.
A relay assembly acts as an electrically controlled switch within the machine's control circuitry. When the control system sends a low-current signal, the relay closes or opens a higher-current circuit — allowing the machine's electronics to safely manage functions such as drive engagement, vibration activation, or safety interlocks without routing high amperage through the control inputs directly. When a relay fails, it can result in circuits that won't energize, functions that won't respond to operator commands, or intermittent electrical faults that are difficult to diagnose. Replacing a faulty relay with the correct OEM unit restores predictable, safe circuit behavior.
