The Wacker Neuson Micro Relay is a genuine OEM electrical component designed for the RD25 and RD15 hydrostatic double drum vibratory rollers. As a direct factory replacement, this relay meets the original electrical specifications required by the machine's control circuitry, ensuring correct switching behavior across the system. Wacker Neuson OEM parts are manufactured to the same standards as the components installed at the factory, so you can install the with confidence in both fit and function. Verified fitment covers the RD25 and RD15 roller series — always confirm your machine's model and serial number before ordering.
Key Features
- Correct Switching Specification — Matches the original coil voltage and contact rating required by the RD25 and RD15 electrical system, preventing misfires or unintended circuit behavior.
- Genuine OEM Sourcing — Produced by Wacker Neuson as a factory-authorized replacement, ensuring the relay integrates directly into the existing wiring harness without adaptation.
- Confirmed Roller Fitment — Engineered for the RD25 and RD15 hydrostatic double drum vibratory rollers, covering both models in this tandem roller series.
- Protects Downstream Electrical Components — A properly functioning relay isolates high-current circuits from sensitive control logic; a failed relay can cause erratic machine behavior or prevent critical systems from energizing.
- Electrical Safety Compliance — Using the correct OEM-rated relay maintains the integrity of the machine's control circuit, reducing the risk of overloading, arcing, or unintended activation of connected systems.
A micro relay is a compact electromechanical switch that uses a low-power signal from the machine's control system to open or close a higher-current circuit. In hydrostatic rollers like the RD25 and RD15, relays are used to control functions such as vibration activation, drive engagement, and auxiliary circuits — allowing the operator's inputs to safely command high-load components without routing full current through the control panel. When a relay fails, the circuit it controls may stop responding entirely, respond intermittently, or remain stuck in one state, which can prevent the roller from operating correctly and complicate diagnosis.
