This unit is one of the several devices from Woodward Inc. Woodward, one of the oldest and leading manufacturers of digital control devices, designed the 505 and 505E model of control units. These devices are built with a microprocessor-based setup to properly operate and streamline steam turbine operations of all sizes.

This unit is designated under the numerical ID of 9907-162. This device is able to run turbines by using one to two of the split-stage actuators in order to drive the inlet steam valves. The 9907-162 is one of the Woodward 505 modules designed to operate single extraction and/or admission applications for steam turbines.

The 9907-162 model, as well as the rest of these series, are designed to be field programmable by the on-site operators on hand. This is achievable by the fully integrated operator control panel on the front facing side of the unit. It is an informational text display which has two lines available, each with 24 characters.

The 9907-162 model also includes an optional NEMA 4X protective casing. While it does keep the internal printed circuitry safe from invasive materials, attaching the protective frame limits the amount of heat that the model can function safely in. This unit is also designed to perform as a first alarm indicator of system shutdowns, which in turn reduces the amount of time spent troubleshooting.

The 505 and 505XT are Woodward’s line of standard off-the-shelf controllers for operation and protection of industrial steam turbines. These user configurable steam turbine controllers include specifically designed screens, algorithms, and event recorders to simplify use in controlling industrial steam turbines or turbo-expanders, driving generators, compressors, pumps, or industrial fans.

Simple to use Simple to configure
Simple to troubleshoot
Simple to adjust (uses new OptiTune Technology)
Simple to connect (with Ethernet, CAN or Serial protocols)

The base 505 model is designed for simple single valve steam turbine applications where only basic turbine control, protection, and monitoring are required. The 505 controller’s integrated OCP (operator control panel), overspeed protection, and trip events recorder make it ideal for small steam turbine applications where overall system cost is a concern.

The 505XT model is designed for more complex single valve, single extraction or single admission steam turbine applications where more analog or discrete I/O (inputs and outputs) are required. Optional inputs and outputs can be connected to the 505XT controller via Woodward’s LinkNet-HT distributed I/O modules. When configured to control single extraction and/or admission based steam turbines, the 505XT controller’s field-proven ratio-limiter function ensures that interaction between the two controlled parameters (i.e., speed and extraction or inlet header and extraction) is correctly decoupled. By simply entering maximum levels and three points from the turbine’s steam map (operating envelope), the 505XT automatically calculates all PID-to-valve ratios and all turbine operation and protection limits.
