9905-020 | Woodward Load Sharing and Speed Control Series

Description 

Woodward's Part 9905-020, belonging to the 2301A Load Sharing and Speed Control Series, is a forward-acting, low-voltage control unit featuring an individual actuator. Notably, it lacks a deceleration ramp function, with the actuator current ranging from 0 to 200 mA. 

During power-up, the unit requires an input power of 20-40 Vdc, necessitating compliance with IEC standards for safety extra-low voltage (SELV) power sources. 

Operating within a temperature range of -40 to +185 degrees Fahrenheit, this model features twenty-nine terminals. Notably, terminals two and three control the minimum fuel contact, essential for normal prime mover shutdown but not intended for emergency stop use.
