WOODWARD 9907-167｜505E Digital Speed Controller｜

Purpose
Product Type: 505E Digital Speed Control Controller (Dedicated for Low Voltage DC)
Core functions: speed closed-loop, load regulation, extraction/inlet pressure control, valve range separation, automatic start stop, critical speed avoidance, overspeed/underspeed protection, first fault memory
Typical applications: Industrial steam turbines, steam turbine generator sets, turbine expanders, marine propulsion steam turbines
Environmental adaptation: Class 1, Div. 2 applicable, standard NEMA 4 protection, optional higher level

Function
Multi mode control: speed, power, pressure, flow rate, valve position, synchronous synchronization, load distribution
Extraction/Inlet Steam Management: Suitable for single extraction, inlet steam, or extraction+inlet steam composite control, supporting split range actuators
Automatic start stop and protection: automatic start in cold and hot states, valve limiting, critical speed avoidance, overspeed/underspeed/overload protection, first fault memory
On site programmable: local button/menu settings, no additional hardware required, supports 505View software configuration
Safety linkage: It can be linked with ETS/overspeed protection system to achieve shutdown and interlocking
