Installation and Setup Guidance
Installing the Woodward 5466-258 requires proper handling to avoid damage. Insert the module into card guides within the control chassis and connect it to the motherboard. Secure it using the two screws on the front panel — one at the top and one at the bottom. Toggle the two handles outward to disengage the connectors for removal. Connect the module to 24 Vdc power and mount it on a DIN rail. Use the internal +24 V connections or an external 24 V source for wiring inputs. Set the module address using the one and ten rotary switches according to your application. For replacement, set the new node’s address to match the faulty one, mount it on the DIN rail, and reconnect terminal blocks. Reset the node via the application program to clear the no-message fault and resume communications.
Compatible Systems and Integration
The Woodward 5466-258 integrates with MicroNet Plus hardware and the Vertex-Pro chassis. It works in both Simplex and Redundant systems, and fits any eight- or fourteen-slot chassis. The module connects to two high-density discrete/analog cables when used with twenty-four/twelve discrete field termination modules. The discrete inputs are optically isolated and accessible through the FTMs. Use this module as a direct upgrade for older Woodward I/O modules in turbine or compressor control applications, ensuring backward compatibility with existing wiring and control software.
Selection Guide and Purchasing Advice
Before purchasing the Woodward 5466-258, verify that your system uses MicroNet series controllers and that the chassis slots match your configuration. Ensure the power supply provides 18 to 32 Vdc and that the environmental conditions meet the 0-55°C operating range.
