The CMR W0034419-283, also known as Caterpillar part number CPN114498, is a robust J1939 CANBUS Interface Module designed for seamless integration with modern engine control systems. This module acts as a vital bridge, reading critical data parameters such as engine speed, oil pressure, coolant temperature, and operating hours directly from the engine’s J1939 data link. It then makes this information available to external monitoring and control systems, such as PLCs, gauges, or annunciator panels. Engineered for reliability in demanding industrial environments, this DIN rail mountable module is an essential component for engine monitoring, generator set control, and various industrial automation applications.
