The Bomag 05767978 Relay is a genuine OEM electrical relay designed for a wide range of Bomag BW-series rollers, including tandem rollers, single drum rollers, and pneumatic tyred rollers. As a direct OEM replacement, this relay is manufactured to the same specifications as the original component, ensuring correct electrical switching behavior and full compatibility with the machine's existing wiring harness and control circuits. This part fits an extensive lineup of BW-series models, including the BW 191 AD-5, BW 213 D-5, BW 226 DH-5, BW 206 AD-5, and many more across the BW 161, BW 174, BW 190, BW 202, BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, and BW 226 series, as well as the BW 28 RH pneumatic tyred roller.
Key Features
- OEM Electrical Specification — manufactured to the original switching capacity, coil resistance, and contact rating for reliable circuit control in demanding compaction equipment environments
- Direct Drop-In Replacement — matches the original connector type and mounting configuration, so this relay seats into the existing relay socket without alteration
- Broad BW-Series Coverage — fits tandem rollers including the BW 161 AD-5, BW 190 AD-5, BW 191 AD-5, and BW 206 AD-5; single drum rollers including the BW 211 D-5, BW 213 D-5, BW 216 DH-5, BW 219 DH-5, and BW 226 DH-5; and the BW 28 RH pneumatic tyred roller
- Protects Downstream Electrical Systems — a correctly functioning relay isolates high-current circuits from control signals, preventing voltage spikes and contact burn that can cascade into costlier electrical failures
- Electrical Safety Integrity — using the correctly specified OEM relay ensures the circuit protection and load ratings match what Bomag engineered into the machine, avoiding unsafe overload conditions
A relay is an electrically operated switch that allows a low-current control signal — such as input from a switch or controller — to open or close a high-current circuit that powers components like hydraulic solenoids, lights, or starter circuits. In a Bomag roller, relays are integral to the machine's electrical architecture, directing power to key systems at the right moment and protecting sensitive electronics from high-load current. When a relay fails, the circuit it controls either stays permanently open (causing a system to stop responding) or permanently closed (causing unintended activation), both of which can halt operation or create unsafe conditions on the job.
