Technical FAQ

Can the 9905-387 be used with non-Woodward actuators?
The module is specifically tuned for ProAct actuator electrical and mechanical characteristics. Using non-compatible actuators may result in unstable control performance or equipment damage.

How does the fault logging feature help maintenance?
The module stores internal fault and event data, helping technicians identify whether system trips were caused by signal loss, voltage instability, or internal hardware errors without requiring external monitoring tools.
