The Wacker Neuson Relay is a genuine OEM component designed for the RD25 and RD15 hydrostatic double drum vibratory rollers. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original, ensuring a straight-in installation with no guesswork. This relay is sourced through authorized Wacker Neuson supply channels, so you can be confident in its authenticity and fitment accuracy across compatible RD-series roller models.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the original switching and load ratings required by the RD25 and RD15 roller electrical systems, eliminating the risk of incorrect actuation or premature failure.
- Direct-Fit Replacement — Matches the original connector footprint and mounting configuration, allowing straightforward installation into the existing relay position without modification.
- RD-Series Roller Fitment — Confirmed compatible with the RD25 and RD15 hydrostatic double drum vibratory rollers, covering both machine configurations in this tandem roller family.
- Electrical Circuit Integrity — A functioning relay ensures that key machine circuits are switched cleanly and at the correct load; a failed relay can cause controlled systems to stop responding or operate erratically, halting productive compaction work.
- Electrical Safety Compliance — Using a genuine OEM relay rated for the original circuit load protects downstream components from overcurrent and ensures the machine's electrical system operates within its designed parameters.
A relay is an electrically controlled switch that allows a low-power signal — typically from a control switch or ECU — to open or close a higher-current circuit powering motors, solenoids, or other heavy loads on the roller. On the RD25 and RD15 hydrostatic double drum vibratory rollers, relays are used throughout the electrical system to control functions such as vibration, propulsion, and auxiliary circuits. When a relay fails, the circuit it controls stops functioning entirely or behaves intermittently, which can prevent the machine from operating key systems until the faulty component is replaced.
