Frequently Asked Questions - Woodward 505/2301A

What is the difference between the Woodward 505 and 2301A?
The 505 is a single-engine digital governor for speed and load control. The 2301A adds load sharing capability for multiple engines operating in parallel. Both use 9907 series modules.
Which 9907 modules are most commonly needed?
The most requested modules include 9907-164 (505E Digital Governor), 9907-838 (2301A Load Sharing), 9907-147 (505 Speed Control), and associated power supply and I/O modules.
Are Woodward 505 controllers still supported?
Yes, the 505 platform remains widely used and supported. BDB Turbine Parts maintains stock of 9907 series modules and can source replacements for all 505 and 2301A variants.
Can the 505 be upgraded to MicroNet Plus?
Yes, Woodward offers migration paths from 505/2301A to MicroNet Plus for enhanced capabilities. However, many operators continue with 505/2301A due to proven reliability and lower upgrade costs.
Do you offer exchange programs for 9907 modules?
Yes, we offer core exchange programs for many 9907 series modules to reduce costs and lead times. Contact us for exchange pricing on your specific modules.
