Woodward 8516-018 Digital Governor Module

Product Brief Introduction Compact digital governor module for prime mover speed control. It receives rotational speed feedback and outputs control signal to actuator to stabilize engine rotating speed.
Tag:

Technical Specifications 24VDC power supply; magnetic pickup pulse input; analog control output; configurable PID parameters. Operating temperature: -40℃ ~ +85℃.

Functional Features Closed-loop PID speed governing; speed droop adjustment; overspeed monitoring; hardware fault self-diagnosis.

Application Scenarios Small and medium diesel and gas engine genset governing systems.

Performance Parameters Rapid dynamic response during load fluctuation, good governing stability, vibration resistant.

Structural Characteristics Metal shielding housing, DIN rail mounting, pluggable terminal blocks.

Working Principle The module measures real-time rotational speed from magnetic pickup sensor, compares actual speed with target setpoint, computes control signal to adjust actuator stroke and fuel supply.

Installation Requirements Install in sealed control cabinet; use shielded twisted pair cable for speed sensor wiring.

Usage Notes Tune governing PID parameters on site; backup parameters before adjustment.
