WOODWARD 5464-340 is an expansion module designed by Woodward for industrial automation systems.It is mainly used to expand input/output(I/O)functions,support collaboration with core controllers(such as the 5461 series),and realize data acquisition and control signal transmission of complex systems.The following are its core functions and technical features:
1.Core functions
I/O expansion capability:
Provides digital input/output expansion,supports 24V DC or 4-20mA signals,can connect sensors,actuators and external devices,and meet multi-parameter acquisition and control requirements.
Communication and compatibility:
Supports industrial protocols such as Modbus and Profibus,and can seamlessly connect with Woodward 5461 series controllers to achieve data exchange and remote configuration.
Redundant design:
Some models support hot-swap and redundant configuration to improve system reliability and are suitable for uninterrupted operation scenarios.
2.Technical features
Industrial protection:
Adopting IP30 protection design,the operating temperature range is-40℃to 70℃,and the anti-electromagnetic interference capability complies with the IEC 61000 standard,which is suitable for harsh industrial environments.
