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-Straight has offered HDCombo modules, mainly for spare parts and system upgrades, and to drive 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. 5466-36-1 can be used in retrofit systems that require the specific I/O and FTM provided by this module.
