Overview
The ECU-SS30 is an engine overspeed protection module designed to monitor engine RPM and trigger an emergency shutdown when speed exceeds the preset threshold. It provides an independent safety layer separate from the primary speed governor, ensuring the engine cannot run away in the event of governor failure, fuel rack jam, or sudden load loss. Widely used in diesel and gas generator sets where overspeed protection is required by safety regulations.
Key Features
- **Independent Overspeed Monitoring** — Separate magnetic pickup input monitors engine RPM independently of the main speed controller
- **Adjustable Trip Threshold** — User-configurable overspeed setpoint via onboard potentiometer
- **Fail-Safe Shutdown Output** — Relay output energizes to run, de-energizes on overspeed for fail-safe fuel cut-off
- **Manual Reset** — Requires manual reset after trip to prevent unattended restart after a safety event
- **LED Status Indication** — Front-panel LED indicates normal operation, overspeed trip, and power status
- **Wide Supply Voltage** — Operates on 12V DC and 24V DC generator battery systems
