Product Introduction

The ABB CMA120, part number 3DDE300400, is a basic controller panel unit belonging to ABB SYNPOL D series. It acts as the human-machine operation and control core for generator and motor protection & control systems. This integrated panel combines LCD display, membrane keyboard and main control circuit board, enabling operators to view real-time operating parameters, set control parameters, check alarm information and execute manual control commands directly on site. Built with industrial electronic components and reinforced anti-interference design, it can run steadily under harsh industrial environments with temperature variation, dust, vibration and strong electromagnetic interference. Widely applied in power generation, generator set control, industrial motor control and energy automation fields. It serves as critical spare part for SYNPOL D system maintenance, panel replacement and power equipment renovation projects.

Brand: ABB Model: CMA120 Part No: 3DDE300400 Product Type: SYNPOL D Basic Controller Panel Series: SYNPOL D Generator & Motor Control System The ABB CMA120 3DDE300400 controller panel is the local operation interface for ABB SYNPOL D control system. It collects real-time data such as voltage, current, power, power factor and frequency from the generator or large motor control unit, and presents these data on the built-in LCD screen for on-site operators. With the integrated keypad, users can modify system parameters, switch control modes, reset alarms and carry out local manual operation without relying on upper monitoring workstation. It is equipped with standard serial communication interfaces to exchange data with back-end control boards and remote monitoring systems. Reliable data transmission ensures synchronization between local panel display and backend control logic. Every unit undergoes comprehensive function test and aging screening before delivery, lowering failure risk under long-term continuous operation. Excellent EMC electromagnetic compatibility helps resist interference generated by high-power power equipment in power plants. This unit adopts panel mounting structure, easy to install and replace on the control cabinet. It supports built-in fault diagnosis function, and alarm indicators will light up when system abnormalities occur, helping maintenance staff quickly locate faults and shorten equipment downtime. Typical application scenarios include hydroelectric and thermal generator control, large industrial synchronous motor protection, power station auxiliary machine control and energy management automation. When the original SYNPOL D controller panel fails, CMA120 3DDE300400 can be used as direct replacement spare part to restore local monitoring and operation functions of the whole generator control system. It complies with international industrial safety and power industry standards, with stable display performance and long service life. Whether you prepare spare inventory for power equipment overhaul or purchase components for power automation retrofit projects, this ABB CMA120 3DDE300400 controller panel provides reliable local control and monitoring function for your SYNPOL D system.
