Electronic Engine Control DC50D DC52D DC50DR DC52DR MK3 Diesel Generator Set Controller Color DC50D Product overview A compact genset controller designed for Diesel, Gasoline and Gas generator sets. Provides automatic start and stop, real time parameter monitoring, fault detection and configurable protection logic. The user interface uses a 3.5 inch resolution display and a silicone front panel for reliable operation in industrial environments. Settings can be made from the front panel or remotely via USB or RS485 using MODBUS. Key benefits Reliable automation for single or mains paired gensets, reducing manual intervention and response time when faults occur. Clear fault display and automatic shutdown when operation is unsafe, protecting the engine and connected equipment. Flexible integration options for local control or remote monitoring and control via standard communication protocols. Simple configuration and language options to suit different operators and installations. Main features Models: DC50D MK3 for single machine automation; DC52D MK3 adds mains monitoring and AMF automatic mains to generator switching; DC50DR MK3 adds RS485; DC52DR MK3 adds both mains AMF and RS485. Processor: dual core 32 bit performance microcontroller for fast response and stable control. Display: 3.5 inch 240 x 128 resolution screen with UI graphics and numeric indicators for easy reading of parameters and alarms. Languages: Chinese and English available, up to six languages supported on request. Controls: silicone front panel buttons for all parameter changes and local operation. Ports: USB port for parameter setup even when controller power is off and for real time monitoring; RS485 port for remote monitoring and Three Remote functions using MODBUS protocol. Protection: simultaneous display of multiple faults and automatic shutdown when smooth operation cannot be maintained. I O visibility: input and output status display directly on the screen. Materials: acrylic screen protection and durable silicone keypad. Real time clock for accurate event logging and scheduled operations. Performance and compatibility Designed for Diesel, Gasoline and Gas generator sets of varying sizes. Supports remote start and stop signals and automatic transfer when mains monitoring is enabled. Real time parameter display and fault checking suitable for continuous monitoring and automatic control applications. Configuration and operation Configure parameters locally via front panel or remotely with USB or RS485 connection to a PC. MODBUS protocol support enables integration with SCADA or building management systems. Language and display settings adjustable to operator preference. Typical applications Backup power for commercial buildings with automatic mains to generator switching using DC52D MK3 or DC52DR MK3. Remote generator farms or distributed generation sites requiring centralized monitoring and control via RS485 MODBUS using DC50DR MK3 or DC52DR MK3. Construction or rental generator deployments where single unit automation and remote start stop are required using DC50D MK3. What is included Controller unit with silicone front panel and acrylic screen protection. USB interface for parameter setup and monitoring. RS485 available on DR models for remote communication. Note All model names and functions are preserved as DC50D, DC52D, DC50DR and DC52DR MK3. Parameters and language packs can be customized on request.
