Generator Engine Controller Module replaces DSE501K Package included 1x Generator engine controller module What this module does Provides reliable engine control for generator sets, handling start and run relay functions and alarm signaling. Monitors alternator and magnetic pickup inputs to ensure accurate speed sensing and protective tripping. Compact front panel mounting design makes it suitable for retrofits and installations. Key benefits Broad input compatibility: alternator voltage input accepts 15 to 305 V AC RMS and frequency 50 to 60 Hz at rated engine speed, covering a wide range of alternator types. Flexible magnetic pickup support: accepts 0.5 V to plus or minus 80 V and magnetic frequencies from 2300 Hz to 6000 Hz at rated engine speed, enabling use with many sensors. Robust operating range: designed to operate from minus 30 degrees C to plus 70 degrees C for reliable performance in varied environments. Easy installation and calibration: front panel mounting via a standard cutout with retaining clips supplied; cable connections use locking plug and socket type connectors; speed trip setting and meter calibration potentiometers are accessible from the rear of the module. Strong relay outputs: Start and Run relays rated 16 Amp DC at supply voltage, Alarm output rated 1 Amp DC at supply voltage for clear control and signaling.
