9907-018 | Woodward 2301A Speed Control Module

Product Description

Configured for precise governor and speed management tasks in prime mover systems, the Woodward 9907-018 (9907-018/2301A 2301A speed control module) provides direct physical/electrical execution.

Hardware Specifications

Actuator Loop Feedback Response and Governing Dynamics

The unit operates from a certified SELV-compliant 20 V to 40 V DC power source, utilizing a single printed circuit board housed within a durable sheet-metal chassis. All calibration potentiometers are accessible directly from the front panel for field tuning. The module governs diesel engines, gasoline engines, and gas or steam turbines by driving proportional actuators through its 2 A maximum output stage. Isochronous control mode ensures constant prime mover speed for isolated bus configurations or base loading against an infinite bus when integrated with external accessories such as Automatic Power Transfer and Load (APTL) or Import/Export controls. Alternatively, droop mode provides speed control as a function of load for single-prime-mover operation on an infinite bus or standard parallel generation architectures.

Frequently Asked Questions

Q: What power supply certification is required for operating the 9907-018 module?

A: The input power must be supplied from an external power supply or battery charger certified to IEC standards with a Safety Extra Low Voltage (SELV) classified output.

Q: How is speed feedback supplied to the module?

A: Speed feedback is accepted via a frequency input ranging from 50 Hz to 10 kHz, corresponding to the monitored rotational velocity of the prime mover.

Q: Can this unit handle parallel generator configurations?

A: Yes, the module supports both isochronous load sharing on an isolated bus and droop mode operation for parallel load sharing across multiple prime movers.

Field Installation Guidelines

• Verify that the input supply voltage remains strictly within the 20 V to 40 V DC range and maintains SELV classification prior to energizing the unit.
• Mount the sheet-metal chassis securely within an environment conforming to the standard operating temperature range of -40 deg C to +85 deg C.
• Ensure all analog load sharing lines (0-10 V or 4-20 mA) and speed feedback wiring utilize properly shielded cables to mitigate electromagnetic interference in industrial electrical environments.
• Adjust front-panel accessible potentiometers carefully during commissioning to optimize governor stability and load-sharing deviation parameters within rated limits.
