Integrated Solutions
The 8440-1831 module integrates seamlessly with complementary Woodward control products to form complete power management systems. Engineers frequently pair this breaker control with the Woodward 8273-128 Load Sharing & Speed Control Module for coordinated governor and breaker operation, the Woodward 8923-1262 DSLC-2 Digital Synchronizer for advanced phase-matching algorithms, and the Woodward 9903-543 AGLC Automatic Generator Loading Control for intelligent load distribution across multiple gensets.
Common Questions
Q: Can the 8440-1831 control multiple circuit breakers simultaneously?
A: The module is designed to control a single circuit breaker per unit. For multi-breaker applications, deploy multiple 8440-1831 modules networked via Modbus RTU for coordinated operation.
Q: Is this module compatible with non-Woodward governors?
A: Yes, the 8440-1831 accepts standard analog and digital inputs, allowing integration with third-party speed governors and voltage regulators through configurable I/O mapping.
Q: What breaker types are supported?
A: The module supports motorized circuit breakers with shunt trip and close coils, including ABB, Schneider Electric, Siemens, and GE breaker models commonly used in generator applications.
Q: How is synchronization accuracy maintained?
A: The microprocessor continuously monitors voltage magnitude, frequency, and phase angle differences, executing breaker closure only when all parameters fall within user-defined synchronization windows (typically ±5° phase, ±0.2 Hz frequency).
