6G Controls - Leading Supplier of New & Original PLC 、DCS Parts and Automation Controller
Product Overview
The 5466-328 module is a versatile control I/O component engineered for Woodward MicroNet™ and MicroNet Plus control platforms. Depending on firmware, backplane assignment, and system architecture, this unit can operate as an analog input solution, a mixed analog combination module, or a multi-channel digital output interface.
Designed specifically for mission-critical energy and turbomachinery systems, the 5466-328 supports precise signal acquisition and reliable actuator control under continuous industrial duty. Its flexibility allows system integrators to deploy the same hardware across multiple control strategies while maintaining platform consistency.
System Compatibility
The 5466-328 integrates directly with Woodward MicroNet™ and MicroNet Plus controllers, including redundant and TMR (Triple Modular Redundant) architectures. Dual-port communication support enables deterministic data exchange and fault-tolerant operation in high-availability control systems.
