Product Overview

The ABB CMA112, identified by part number 3DDE300013, is a specialized diesel control display and communication interface designed for the AC500 automation platform. This unit serves as a high-visibility front-panel gateway, allowing operators to interact directly with diesel engine control parameters and system diagnostics. Engineered for high-speed data exchange, the CMA112 synchronizes real-time engine metrics—such as RPM, fuel consumption, and thermal status—with the broader Distributed Control System (DCS). Its robust construction is tailored for the high-vibration and electrically noisy environments typically found in power generation and marine engine rooms, ensuring that critical monitoring data remains accessible and accurate during continuous operations.

Industrial Deployment and Site Applications

The CMA112 3DDE300013 is primarily deployed in mission-critical energy sectors, including standby power facilities, offshore drilling rigs, and marine propulsion control. Within an AC500 architecture, the panel acts as a bridge between the engine's Electronic Control Unit (ECU) and the supervisory automation layer. Its 0.7kg compact design allows for easy mounting on generator set control cabinets, providing a localized point of entry for technicians to perform system startups or emergency overrides. By supporting advanced diagnostic feedback, the module reduces the time required for troubleshooting sensor irregularities or communication drops. This ensures that massive diesel assets—whether providing emergency hospital power or driving heavy industrial pumps—operate with maximum fuel efficiency and minimal risk of unplanned shutdown.
