Woodward 8250-501 Speed Control Module

Product Brief Introduction Digital speed governing module for prime mover speed regulation. It receives magnetic pickup speed pulse signal and generates control output to actuator driver for stable speed control under varying load.
Tag:

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

Functional Features PID closed-loop speed governing; adjustable speed setpoint; overspeed monitoring and alarm; channel fault self-diagnosis.

Application Scenarios Gas engine and diesel genset speed governing control loops.

Performance Parameters Fast response to speed deviation, high governing precision, stable operation under vibration environment.

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

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

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

Usage Notes Backup governing parameters before modifying settings; anti-static protection required for replacement.
