The Wacker Neuson Relay is a genuine OEM component designed for the RD15 and RD25 hydrostatic double drum vibratory rollers. As a direct OEM replacement, this relay is sourced to the original specification, ensuring correct electrical switching behavior for the circuits it controls on these tandem roller platforms. Verify your model number against the RD15 and RD25 fitment before ordering to confirm this is the correct relay position for your machine.
Key Features
- OEM-Spec Switching Capacity — Engineered to the original coil resistance and contact rating, so the relay opens and closes circuits at the correct load thresholds for RD15 and RD25 electrical systems.
- Drop-In Terminal Compatibility — Matches the original connector housing and pin configuration, allowing direct installation into the existing relay socket without modification to the wiring harness.
- Fits RD15 and RD25 Tandem Rollers — Confirmed fitment for both the RD15 (5000008057) and RD25 (5000008058) hydrostatic double drum vibratory roller models.
- Protects Downstream Electrical Components — A functioning relay isolates high-current circuits from control-side signals; a failed relay can cause erratic operation, stuck functions, or prevent the machine from starting or running correctly.
- Genuine Wacker Neuson OEM Part — Supplied as an original equipment component under part number 5000112529, meeting the electrical standards set for this roller series.
A relay is an electrically operated switch that uses a low-current control signal to open or close a higher-current circuit within the machine. On tandem rollers like the RD15 and RD25, relays are used throughout the electrical system to manage functions such as starting circuits, drum vibration control, and auxiliary outputs. When a relay fails, the circuit it controls may become unresponsive or may stay permanently open or closed, leading to functions that won't activate or won't shut off — both of which can halt productive work and put stress on connected components.
