DC30D Remote Start Controller for Gas Generator Auto Start Control Module Overview The DC30D is a compact automatic start and monitoring controller designed for small diesel, gasoline, and gas generator sets. It provides reliable start, stop, monitoring, fault detection, and parameter configuration for automatic genset control systems. Key benefits Reliable automatic control for unattended generator operation, reducing manual intervention and response time. Onboard fault detection and multifault display to identify problems quickly and initiate safe shutdown when needed. Flexible configuration via frontpanel buttons or USB connection to a PC for easy setup and adjustment. Compact panelmount size for straightforward installation in control panels and equipment enclosures. Core functions Automatic start and stop of generator sets. Realtime monitoring of speed, voltage, and frequency. Multifault detection and display; automatic stop if the genset cannot operate smoothly. Parameter setting through front buttons or PC via USB. Language options include Chinese and English; additional languages available on request. Technical specifications Operation voltage: DC 8 to 36 V continuous.
