The devices listed here are models 9907-164 and are part of the 505 and 505E governor control units based on microprocessors. These control modules are designed for the operation of steam turbines as well as turbogenerator and turboexpander modules. The 505/505E series was originally developed, produced and manufactured by the Woodward Company. Woodward is America’s oldest industrial manufacturer, founded in 1870, and remains one of the leading industrial companies in the market today. These 505 and 505E models are available from our AX Control Inc. Acquired as part of our used but refurbished and repaired digital hardware inventory.

9907-164 Edge controller equipment uses new IT communication and Internet of Things technology, while retaining PLC/PAC in OT edge controller communication has two different levels: one is the acquisition of industrial equipment and process data I/O, and communication with other industrial control equipment, belongs to the OT category; The other is the communication between edge devices and OT data centers and cloud servers, which belongs to the category of IT, that is, the category of industrial Internet. As a physical interface between IT and OT, on the basis of completing the control functions of workstations or production lines, the interface capability and computing power of industrial equipment are improved, and the applicability of industrial equipment is improved. Therefore, the integration of IT and OT can be promoted to a certain extent. Therefore, the combination of edge controller technologies can meet a variety of application needs, so it is very suitable for industrial applications. Unlike traditional PLCS, edge controllers are able to provide connectivity solutions, including acting as OPC or message queue telemetry Transfer (MQTT) servers.

The 9907-164 unit is designed to control a steam turbine by operating a single extraction and/or steam turbine. It uses one or both of the turbine’s separate stage actuators to drive the steam inlet valve.

The unit, like any 505 governor module, can be configured in the field by a field operator. Menu-driven software is controlled and changed by an operator control panel integrated on the front of the device. The panel displays two lines of text, each of 24 characters.

The 9907-164 is equipped with a range of discrete and analog inputs: 16 contact inputs (four of which are dedicated, 12 of which are programmable), followed by six programmable current inputs ranging from 4 to 20 mA. Standard features included in the 9907-164 feature include critical speed avoidance, valve position limiter, automatic start sequence, and stop-first out indicator.
