Key Features

• Dual Power Input Flexibility: Supports HV (115/240 Vac, 125 Vdc) and LV (24 Vdc) power sources, adapting to diverse site electrical configurations.
• Independent Trip Relays: Three independent Form - C relays enable custom alarm/trip mapping without voting logic, simplifying integration with existing shutdown systems.
• Sulfur - Resistant Design: Conformal coating protects internal components from H₂S/SO₂ corrosion, extending service life in petrochemical and offshore applications.
• Automatic Overspeed Testing: Performs routine overspeed tests without turbine shutdown, validating system functionality while minimizing operational downtime.
• MPU Integrity Checks: Continuously verifies magnetic pickup connections and signal quality, triggering alarms for faulty sensors before speed monitoring errors occur.
• Modbus Integration: RS485 - based Modbus RTU enables remote monitoring, data logging, and parameter adjustment via SCADA systems.
• Real - Time Speed Readout: 4 - 20 mA analog output provides proportional speed data for operator visualization and control system integration.
• Panel - Mount Convenience: Compact form factor fits standard control cabinets, with front - panel keypad/display for local configuration.

Key Features

• Microprocessor-Based Control: Ensures precise speed regulation and load sharing with steady-state accuracy to optimize engine efficiency.
• Dual Serial Ports: RS-232/RS-422 enable PC-based configuration, data logging, and remote monitoring for operational flexibility.
• PWM Actuator Output: Low-current PWM signal directly drives fuel/air actuators for responsive engine control.
• Soft Load Transfer: Prevents voltage/frequency transients during generator on/off-load transitions to protect electrical loads.
• Multiple Dynamic Adjustments: Configurable parameters for acceleration, deceleration, and load response to match pump/compressor dynamics.
• Automatic Idle Function: Reduces engine speed during no-load periods to lower fuel consumption and wear.
• Legacy Compatibility: Direct replacement for 8273-101 with identical mounting/wiring to minimize retrofit costs.
• Hazardous Location Rating: Class 1, Division 2 certification for safe operation in petrochemical/refinery environments.
