WOODWARD 5501-471 NetCon Serial Input/Output

The WOODWARD 5501-471 is a high-performance intelligent serial I/O and communication gateway module for the NetCon™ control platform (compatible with MicroNet™ systems). 

It acts as a bridge between the NetCon controller and external serial devices, handling multi-protocol communication, analog/digital I/O, 

and system diagnostics for gas/steam turbines, reciprocating engines, and generator control systems. Designed for redundant, reliable operation in 

harsh industrial environments (power generation, oil & gas, marine), it enables seamless integration with SCADA, HMIs, and third-party systems.
