Technical description: 5466-31 6 WOODWARD HDCombo module microgrid TMR system
The MicroNet 5466-253 and 5466-316 HDCombo modules were first introduced in 1997 for the steam control market. The module includes 8 analog inputs and 4 analog inputs
Outputs, four speed inputs, and two proportional actuator outputs. The -253 version has the ideal combination of TMR and 5009 system control valves with proportional actuator I/O.
Woodward’s latest speed/analog combination module (5466-1115) lacks the on-board proportional actuator feature of the older HDCombo module, requiring the addition of a separate dual channel
Actuator module. This eats up valuable I/O space in the main TMR chassis. Since 2016, Woodward has been offering HDCombo modules, mainly for spare parts and system upgrades, and to push steam
Steam and compressor customers use the 5466-1115 as well as the complementary 2CH actuator control module. Woodward’s 5009 standard turbine control was also changed to utilize a newer combination module.
From the end of 2020, the standard 5009XT turbine control will be replaced by 5466-253 HDCombo modules instead of 5466-1115 Combo modules. Custom programming
Microgrid TMR systems can be used in either configuration. Woodward recommends using 5466-253 on the TMR system if the turbine uses proportional actuators, and using 5466-1115 if the turbine makes
With integrated actuators or separate servo controllers, such as SPC. The 5466-316 can be used in retrofit systems that require the specific /O and FTM provided by this module.
