Woodward 9906-130 Digital Governor Module

Product Brief Introduction DIN rail mounted digital governor module for prime mover speed and load regulation. It processes rotational speed feedback signals and generates control outputs to adjust actuators to maintain stable prime mover speed under varying load conditions.
Tag:

Technical Specifications 24VDC operating power; pulse speed signal input; analog control output channel; built-in EMC filter. Operating temperature: -40℃ ~ +85℃.

Functional Features Closed-loop PID speed governing; speed setpoint adjustment; overspeed monitoring and alarm; channel fault diagnosis.

Application Scenarios Medium and small gas engine and diesel generator speed governing control loops.

Performance Parameters Quick response to speed deviation, high governing accuracy, stable continuous operation under vibration environment.

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

Working Principle The module receives real-time speed pulse feedback, compares actual speed with setpoint value, calculates control output via internal PID algorithm and sends commands to actuator driver to adjust fuel or gas valve opening.

Installation Requirements Install in sealed dust-proof cabinet; separate speed signal cable and high-power cable.

Usage Notes Backup governing parameters before modification; use anti-static measures during module replacement.
