Brief Product Description

WOODWARD 8200-1301 is a high-precision 505D field-programmable digital turbine governor controller designed for industrial steam turbine speed and load regulation. Featuring an integrated graphical display and menu-driven operation software, this all-in-one governor delivers stable, accurate control for single-valve and split-range actuator turbine systems. It supports wide-range AC/DC universal power input and complies with hazardous area installation standards for Class I Division 2 environments. Built with advanced signal processing, closed-loop regulation and comprehensive turbine protection logic, the 8200-1301 ensures safe, efficient and reliable turbine operation during startup, synchronization and variable load conditions. It can operate as a standalone controller or integrate seamlessly with DCS systems. Fully tested surplus and refurbished WOODWARD 8200-1301 units are available for legacy turbine control system maintenance, replacement and retrofit projects.

FAQ (Frequently Asked Questions)

• Q: Turbine speed instability or load fluctuation after installing 8200-1301?
  A: Recalibrate speed sensor signal parameters, verify actuator stroke matching, check power supply stability, and optimize PID control and load limit settings.
• Q: Does WOODWARD 8200-1301 support hot-swap replacement?
  A: Hot swap is not allowed. Shut down turbine operation and cut off controller power to avoid sudden speed surge or unit trip faults.
• Q: What power supply does the 8200-1301 support?
  A: It supports universal 88–264 V AC and 90–150 V DC wide-range power input for industrial field adaptability.
• Q: Can this controller work with DCS systems?
  A: Yes, the 505D governor supports data communication linkage with mainstream DCS platforms for remote monitoring and control.
• Q: Is WOODWARD 8200-1301 available for new turbine projects?
  A: This legacy digital governor is end-of-life for new projects. Fully tested surplus and refurbished units are supplied for existing turbine system maintenance and retrofits.
