Product Introduction
When a critical communication failure threatens system integrity, the Woodward 5464-654 Discrete Output Module provides a failsafe response: outputs automatically turn off if contact with the CPU is lost. Developed by Woodward, the 5464-654 is a 32-channel digital output module designed for MicroNet control systems. It receives digital data from the CPU and generates relay driver signals, interfacing with Woodward Relay Modules to control prime mover outputs. The 5464-654 requires no calibration and features two different FTM I/O configurations.

The 5464-654 provides fast 5 ms update time, ensuring responsive control actions. With 32 independent channels, each module can manage multiple discrete outputs, directly responding to CPU commands. The automatic output shutdown during communication loss prevents unintended actuator movements, enhancing safety in turbine and engine control applications.
Industry Applications
The Woodward 5464-654 Discrete Output Module excels in prime mover control systems. Common uses include gas turbine fuel valve control, steam turbine governor actuation, and engine shutdown circuits. In each scenario, the 5464-654's fast update and fail-safe behavior minimize downtime and protect equipment. For example, if a communication link to the CPU drops, the 5464-654 immediately de-energizes its outputs, preventing potential overspeed or unsafe conditions.
Installation & Setup Guidance
Install the Woodward 5464-654 by inserting it into card guides within the MicroNet chassis, connecting it to the motherboard. Secure the module with two screws at the top and bottom of the front panel. Two handles on the module allow easy toggling outward to disengage the boards from motherboard connectors—ideal for replacement. The 5464-654 uses a low-density discrete cable to link to a Woodward Relay Module, which can be daisy-chained to a second module. Note: this module does not provide the separate 24 Vdc power required by the relays; use a section of a multi-output main power supply or a single-output supply.
Maintenance & Reliability
The Woodward 5464-654 requires no calibration and has no potentiometers to adjust. Periodic inspection of the card guides, screws, and cable connections is recommended to ensure reliable operation. Environmental conditions should remain within the MicroNet system's specified range to prevent overheating or vibration damage. Because the 5464-654 can be replaced with any same-part-number module without configuration changes, downtime is minimized—an important cost-saving feature for continuous processes.
Selection Guide & Purchasing Advice
Before purchasing the Woodward 5464-654, verify compatibility with your MicroNet control system and ensure you have the correct Woodward Relay Module and a suitable 24 Vdc power supply for the relay side.
