The 5466-336 is a High-Density Discrete Input Module designed and manufactured by Woodward for use in MicroNet and MicroNet Plus digital control systems. Functioning as a high-speed contact state monitoring card, it ingests digital telemetry from field switches, emergency shutdown buttons, breaker auxiliary contacts, and permissive interlocking relays. By converting binary field signals into synchronized digital status data for the system backplane, the 5466-336 enables accurate sequence-of-events (SOE) tracking and safety interlock execution for gas turbines, steam turbines, and industrial engine controls.
OPTICAL ISOLATION & CONTACT DEBOUNCE PROTECTION:
Built for harsh power plant and oil & gas control environments, the 5466-336 utilizes high-density optical isolators to separate field wiring loops from central system processing logic up to 500 VDC. Onboard hardware noise filtering suppresses false contact transitions caused by mechanical switch bounce, electromagnetic interference (EMI), and ground potential shifts in substation environments. This ensures reliable binary state transmission even when monitoring contacts over long field cable runs.
FIELD SUPPLY AUDITING & INTERLOCK DIAGNOSTICS:
To guarantee critical trip and interlock monitoring, the Input Module includes continuous field power supply and loop integrity checking. Front-panel LEDs provide immediate visual status for every input channel, simplifying commissioning testing and routine loop troubleshooting. If external contact wetting voltage drops below operational thresholds or a field wire opens, the module immediately reports a channel error to the primary CPU, allowing governor software to execute protective fallback logic and preserve safe turbine operation.
