WOODWARD 5461-002 is a high-performance industrial relay module launched by Woodward,designed for complex automation systems,supporting high-reliability signal switching and safety circuit control.The following are its core functions and technical features:
1.Core functions and technical parameters
Relay output type:
Provides 8 independent relay outputs,supports normally open(NO),normally closed(NC)and conversion contact modes,single-channel rated current 10A 250V AC,suitable for motor start and stop,solenoid valve control and other scenarios.
Communication interface:
Integrated RS-232/RS-485 communication port,supports Modbus RTU protocol,and can be seamlessly connected with PLC,DCS system and host computer.
Protection and environmental adaptability:
Industrial protection level IP30,operating temperature range**-40°C to 70°C**,wide temperature model supports**-40°C to 85°C**,and anti-electromagnetic interference capability complies with IEC 61000 standard.
2.Technical advantages
High reliability design:
Redundant power input(12~48V DC)is adopted,dual power supply backup is supported,and MTBF(mean time between failures)exceeds 50,000 hours.
Built-in hardware watchdog and overvoltage protection circuit to avoid abnormal signal interference and malfunction.
Fast response capability:
Contact switching time is less than 10ms,which meets high-speed control requirements,such as servo system positioning or emergency shutdown logic.
Modular expansion:
Supports collaboration with other Woodward modules(such as 5441-407,5453-278)to form a distributed control system.
3.Application scenarios
Energy and power system:
As the emergency shutdown circuit of the diesel engine speed governor,it responds to sensor fault signals and cuts off the fuel supply.
Cooperate with the gas turbine control system to realize safety interlock logic(such as over-temperature and over-pressure protection).
Intelligent manufacturing:
Manage discrete control tasks such as motor start and stop,fixture action,etc.in the robot workstation.
In LED sorting equipment,control the action of the rejection mechanism and the linkage with the production line.
Shipbuilding industry:
Integrated into the main engine remote control system to execute safety-critical commands such as navigation light switch and steering gear control.
