Core Technical Parameters and Functions

The module is well known for its versatility and high reliability. Its main technical features include:

Control Functions

• Load Sharing: Supports load sharing between engines, including both isochronous (synchronous) and droop modes. It is widely used in systems driven by multiple engines operating in parallel.
• Automatic Start Sequencing: Provides automatic sequencing for both hot and cold starts.
• Speed and Load Control: Equipped with redundant speed inputs (magnetic pickup sensors, eddy-current probes, or proximity probes) and offers high-precision load regulation.

Communication and Interfaces

• Communication Protocols: Supports multiple industrial communication protocols, including Modbus, CANopen, and TCP/IP, enabling easy integration with DCS (Distributed Control Systems).

Input / Output

• Analog Outputs: Provides 0–10 VDC or 4–20 mA analog outputs.
• Relay Contacts: Typically equipped with multiple Form-C relay contact outputs.
• Communication Ports: Supports industrial communication interfaces such as RS-485.

Environmental Adaptability

• Operating Temperature: −40 °C to +85 °C (some sources specify up to 158 °F).
• Vibration Resistance: Optimized design to withstand vibration and shock levels up to 6.8 G or 40 G, making it suitable for harsh industrial environments.

Typical Application Scenarios

• Generator Sets: Used to control industrial steam turbines, small-grid turbine generators, or turbo expanders.
• Aerospace and Energy: Applied in aircraft engines, gas engines, and energy management systems.
• Industrial Automation: Used in robotic joint drives, valve control, and other systems requiring precise position or speed control.
