Overview
The DSE7320 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
- Auto Start with AMF — Automatic mains failure detection and generator start/stop with programmable crank/rest cycles for single generator sets
- 7-inch Color TFT Display — Large high-resolution screen with generator/mains mimic diagram, analog instrument gauges, and multi-language support
- CANbus J1939 Engine Interface — Direct connection to electronic engines via J1939 with read/write capability for ECU parameters and diagnostic codes
- USB & RS485 Configuration — Front-panel USB for firmware updates and configuration file upload; RS485 Modbus RTU for remote SCADA integration
- Comprehensive Instrumentation — Real-time display of all AC parameters (V, A, Hz, kW, kVA, PF, kWh) plus engine parameters from CANbus or analog senders
- Programmable Maintenance Scheduler — Hours-run and calendar-based maintenance reminders with configurable warning levels and shut-down options

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.
