Woodward 5501-510 is a Field terminal relay (FTR) manufactured by Woodward Governor, Inc. It is a critical component used in a variety of control systems to provide isolation and signal conditioning for analog or digital signals between field equipment and control systems. Common applications include:
Industrial automation systems: Connect sensors, actuators and other field equipment with PLCS, controllers and SCADA systems.
Aerospace and Defense Systems: Connecting sensors and actuators in flight control systems, weapon systems, and other critical applications.
Test and measurement systems: Connect test equipment to sensors and actuators for data acquisition and control.
Main functions:
The Woodward 5501-510 FTR has several basic functions in these applications:
Signal isolation: It electrically isolates field device signals from control system circuits to prevent electrical noise, ground failures, and other hazards.
Signal conversion: Depending on the model and application, an analog signal can be converted to a digital signal and vice versa.
Signal scaling: It scales the input signal to match the voltage or current range required by the control system.
Surge protection: It protects FTR and connected devices from power surges and transient voltages.
Fault detection: Monitors faults in field equipment signals and provides fault indications to the control system.
