733 Digital Control

The Woodward 733 Digital Control manages and controls reciprocating engines (gas, diesel, dual fuel) used in power generation, marine propulsion, locomotive and industrial engine, and process markets. It has been designed to enable to be mounted directly on the engine or inside control cabinets. The 733 is available as a stand-alone speed control and is the main control unit within an engine management system. Designed for network connectivity, it may be programmed to perform all engine functions: speed, air and fuel control, monitoring, alarms, engine protection and sequencing

723+ Digital Control

The Woodward 723 Plus Digital Control manages and controls reciprocating engines (gas, diesel, or dual fuel) used in power generation, marine propulsion, and gas compression/distribution. The control may also be used in cogeneration, power transmission/distribution, process management, pipeline pump stations, utility power generation, emergency standby power, and remote control station operation. The 723 Plus provides state-of-the-art control for new and retrofit situations.

2301E Digital Load Sharing and Speed Control

Woodward?s 2301E provides load sharing and speed control of generators being driven by diesel or gaseous engines. Using an external computer (PC) and built-in configuration software, application variations may be programmed to accommodate engine speed range, gear teeth, and select forward or reverse acting The 2301E controller is backward compatible with existing 2301D products using the same footprint and mounting configuration with enhanced features.

    2301A Load Sharing and Speed Controls

    The Woodward 2301A Load Sharing and Speed Controls are designed for use in electric generator systems where multi-unit load sharing is desired. 2301A controls may be used with diesel, gas or gasoline engines, or steam or gas turbines. Controls are available for applications requiring droop and/or isochronous speed control; in forward- or reverse-acting models; for single or tandem actuator installations; with accelerating or decelerating ramps; and in several speed ranges. Automatic, adjustable start fuel limiting regulates the maximum fuel setting while the engine is starting.

    2301A Full Authority Speed Control

    The Woodward 2301A Full Authority Speed Control sets the speed or load of a diesel engine, gas engine, steam turbine, or gas turbine according to the demand of a process or a computer control signal. The unit provides isochronous operation, with droop control available through an externally-wired potentiometer. The isochronous mode is used for constant speed of the controlled prime mover as long as it is able to provide power to satisfy the load. Droop control is provided when parallel-bus operation is required.

    UG ACTUATOR

    The Woodward UG-Actuator offers the advantages of electronic control and load sharing systems while using the convenient, existing UG8-type drives and linkages. The actuator provides the muscle for Woodward analog controls such as the 2301A, as well as Woodward digital controls such as the 2301Dand the 723 Plus. The UG-Actuator can be used with diesel or natural gas engines, as well as with steam and industrial gas turbines. The UG-Actuator has a self-contained oil sump so a separate oil supply is not required.

    UG25+

    The Woodward UG-25+ governor is a microprocessor-controlled, mechanical-hydraulic amplified, governor for controlling diesel, gas, and dual fuel engines, and steam turbines. The UG-25+ offers enhanced control capabilities, such as start fuel and boost limiting schemes. The additional transient fuel limiting (jump-rate) improves the engine load acceptance and reduces transient emissions significantly. The UG-25+ concept offers a fast-acting and high-work-output governor, without the need for any auxiliary devices such as a start booster.

    UG8/10

    The UG products are mechanical-hydraulic governors for controlling diesel, gas, or dual fuel engines, or steam turbines. The governor provides extremely reliable speed control throughout the drive speed and temperature range. This proven design has been the industry standard for many years and its worldwide acceptance provides easy service in most engine and governor shops. UG governors (generally known as the “UG-8”) are available in either a UG Dial or UG Lever configuration. Each model is available with any of three different work outputs: UG-5.7: 7.1 N-m (5.2 lb-ft) / UG-8: 13.2 N-m (9.7 lb-ft) / UG-10:15.9 N-m (11.7 lb-ft). UG-Dial governors are particularly suited for constant speed applications. Knob speed settings make synchronization easy for generator applications. Motor speed setting is available for remote synchronization. Adjustable droop makes load sharing between engines precise.
    UG Lever governors are widely used for variable speed control. Remote speed setting can be either mechanical through the speed setting lever or pneumatic with a special speed setting device. Special attachments are available for other applications.
    The UG pump is designed for applications which reverse engine rotation.

    SG Governor

    The Woodward SG governor hydraulic speed-droop type governor is designed for use on small diesel, gas, or gasoline engines where isochronous control is not required. The governor operates at a slower speed as engine load increases achieving system stability and load division between paralleled units.

    PSG GOVERNOR

    The Woodward PSG governor is a pressure compensated, speed-droop or isochronous governor for controlling the speed of small diesel, gas, and gasoline engines, or small steam or industrial gas turbines. The governor is used to control engines or turbines driving alternators, dc generators, pumps, or compressors
