FAQ

Q: What is the difference between 9907-162, 9907-163 and 9907-164?
A: 9907-162: 180–264 VAC; 9907-163: 88–132 VAC / 90–150 VDC; 9907-164: 18–32 VDC low voltage DC version.

Q: Is this 505 or 505E?
A: This is standard 505, for single or split-range actuators; extraction turbines require 505E model.

Q: Is this unit discontinued?
A: Classic 505 series is legacy turbine control hardware, original production stopped, supplied as surplus, refurbished and tested spare parts only.

Q: Can it be used for gas turbines?
A: It is designed mainly for steam turbines; gas turbine control usually uses other Woodward controller series.
