Overview
The HGM9520 is a microprocessor-based generator set controller that provides automatic engine start/stop sequencing, AC power monitoring, and alarm protection for single diesel or gas generator units. It integrates digital measurement, programmable logic, and communication interfaces into a single panel-mounted module.
Key Features
- Microprocessor-Based Control — Advanced MCU with real-time monitoring for generator start/stop, engine protection, and AC parameter measurement
- Multi-Language LCD Display — Backlit LCD with user-selectable languages (Chinese, English, Spanish, Russian, Arabic) for international deployment
- CANbus J1939 Engine ECU Support — Direct communication with electronic engines for real-time parameter display and diagnostic trouble codes
- Flexible I/O Configuration — All digital inputs and relay outputs user-configurable for custom control logic including remote start, pre-heat, and alarm outputs
- USB & RS485 Communication — Front-panel USB for configuration and firmware updates; RS485 Modbus RTU for SCADA/BMS integration
- Comprehensive Engine Protection — Configurable alarm/shutdown for 16 engine parameters with programmable delay timers and warning pre-alarms

Selection Advice
The DSE7320 is Deep Sea’s classic large-screen choice — 7-inch non-touch display with excellent clarity, providing significant advantage in dim generator rooms and for distant viewing. CANopen enables direct communication with high-end engines.
The HGM9520 is SmartGen’s flagship — the most fully-featured: configurable PLC logic, SMS alerts, built-in 4G remote monitoring, unmatched feature set at its price. 12 digital I/O is the highest in its class. Suitable for customers wanting maximum features regardless of brand.
The DKG309 has the smallest screen but the lowest price with the most I/O (10 in, 8 out) and unique SMS functionality. Suitable for utilitarian customers.
