Product Description
Function
The CC-PSV201 is a Series C I/O module designed to provide an onboard PID positioning loop for controlling servo valves, commonly used in turbomachinery control applications. It can:
-
Accept LVDT/RVDT/4-20 mA position feedback signals from the control valve
-
Receive a remote setpoint control valve demand from a C300-20msCEE controller
-
Execute an onboard PID positioning loop
-
Issue current output to the servo valve coil for precise control of the valve position
