Description

ABB CMA112 3DDE300013

ABB CMA112 3DDE300013 is a control and display panel for diesel generating sets, designed as a local human-machine interface unit for diesel generators and marine main/auxiliary engines. It integrates four core functions: real-time parameter display, manual operation intervention, parameter setting, and alarm indication. As an indispensable operation terminal in ABB marine and power plant automation solutions, it is natively paired with the CMA114 3DDE300013 control module. It is widely used in scenarios such as marine engine rooms, offshore platform captive power plants, oil/gas field/mine diesel power stations, and data center backup generator sets. It adapts to harsh industrial and marine environments characterized by limited space, high dust, strong electromagnetic interference, and large temperature fluctuations. With prominent advantages including classification society certification, high vibration resistance, and wide temperature adaptability, it provides convenient and reliable operational support for local operation and maintenance of diesel units.

This panel mainly displays key operating parameters of diesel units (speed, oil pressure, water temperature, load, etc.) in real time, receives local commands from operators (start, stop, emergency stop, speed regulation, alarm reset, etc.), synchronously shows unit operating status and fault alarm information, and stores historical fault records. It achieves seamless data synchronization with the CMA114 control module via a dedicated internal bus. Protection thresholds and control parameters of the CMA114 can be modified directly on the panel without additional configuration tools. It is compatible with the ABB Synpol D diesel control system and 800xA automation platform, and can perfectly match the CMA114 control module as well as various sensors and actuators for diesel units. It complies with international industrial standards and classification society certifications including CE, cULus, DNV, ABS, and LR, ensuring compliance and long‑term operational reliability in marine and industrial applications.

It features a compact industrial sealed design that balances durability and ease of operation. Dimensions are approximately 152mm × 152mm × 76mm (15.2cm × 15.2cm × 7.6cm, official spare part data), weight about 0.7kg (may be 0.64kg in different production batches, subject to physical product). It supports standard flush panel mounting, matching instrument cutout sizes in marine engine rooms and power plant control cabinets. The keypad layout is clear and reasonable, equipped with a backlit LCD display for easy operation and reading in dim environments, suitable for complex on‑site industrial operating conditions.

2. Features

Accurate Display & Convenient Operation
The backlit LCD clearly presents all key operating parameters of diesel units (speed, oil pressure, water temperature, load, etc.) with multi‑page view. Backlight can be activated manually or automatically, suitable for low‑light environments such as night or dim engine rooms.
Rational keypad layout allows operators to directly perform start/stop, speed regulation, emergency stop, alarm reset, and other operations on the panel without additional debugging tools, improving on‑site efficiency.
Native Pairing & Seamless Cooperation
Natively designed as a companion product for the CMA114 3DDE300013 control module. Dedicated bus enables plug‑and‑play and zero‑latency data synchronization.
Protection thresholds (overspeed, low oil pressure, etc.) and control parameters of the CMA114 can be edited directly on the panel without connecting to host software, simplifying commissioning and maintenance and reducing engineering costs.
Clear Alarm & Event Tracing
Upon unit failure, the LCD immediately displays clear alarm text, while corresponding LED status indicators (alarm/fault) flash or stay lit to promptly alert operators.
Supports storage of multiple historical fault codes and event timestamps. Maintenance personnel can query directly on the panel to quickly identify root causes and reduce downtime.
High Reliability & Harsh Environment Adaptability
Industrial‑grade high‑quality components and sealed construction provide excellent EMI and vibration resistance. Certified by major classification societies including DNV, ABS, and LR for long‑term stable operation in harsh marine and industrial environments.
No vulnerable parts; long‑life materials for keys and LCD reduce maintenance frequency.

3. Applications & Case Examples

Marine Main/Auxiliary Engine Display & Control
In engine rooms of bulk carriers and container ships, each diesel generator is equipped with a CMA112 3DDE300013 panel on the instrument panel. Operators can start/stop units, adjust speed, view real‑time parameters, and handle alarms locally. Together with the CMA114 control module and marine PMS, it enables unattended and efficient operation of the marine power plant.
Offshore Platform Captive Power Plant
In diesel power stations on offshore oil and gas platforms, CMA112 panels are installed both in the main control room and locally at the units, providing dual assurance of remote monitoring and local operation. Operators can quickly intervene as needed to ensure stable power supply for platform drilling and living facilities.
Remote Oil/Gas Field / Mine Power Plants
In off‑grid diesel power stations in remote oil/gas fields and mines, operators monitor unit status locally via the CMA112 panel, modify parameters and reset alarms without a laptop, greatly improving O&M convenience in remote areas and avoiding unit failures due to limited maintenance access.
Data Center Backup Diesel Generators
In backup generator rooms of large data centers, CMA112 panels are mounted in control cabinets. When mains power fails, operators quickly confirm unit start status and monitor key parameters during power switching, ensuring uninterrupted operation of servers and core equipment and enhancing data center power supply reliability.
