Key Features
- Genuine OEM Specification — manufactured to the exact electrical and operational tolerances required by Bomag tandem rollers, ensuring the module communicates correctly with the machine's control architecture
- Direct Drop-In Replacement — engineered to match the original mounting configuration and connector interface, allowing a straightforward swap without additional adaptation
- Broad Tandem Roller Coverage — fits BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ADH, BW 135 AD, BW 138 AC, BW 138 AD, BW 138-AD, and related variants, covering a wide range of Bomag tandem roller models
- Restored Machine Control — a failed or malfunctioning module can interrupt compaction control functions; installing this genuine replacement restores normal operational response and output accuracy
- Electrical System Integrity — as an OEM part, this module carries the correct input/output characteristics to prevent signal errors or system faults that can arise from mismatched replacement components
A module in a Bomag tandem roller functions as an electronic control unit responsible for processing signals between machine systems — managing functions such as compaction output, drive control, or operator interface inputs depending on its position in the machine's electrical architecture. When a module fails, operators may experience erratic machine behavior, loss of specific control functions, or fault codes that prevent normal operation. Replacing a faulty module with a correct OEM unit restores proper communication between systems and returns the roller to full working capability.
