WOODWARD 9907-1342｜Current Pressure Converter｜illustration

Model: 9907-1342
Product Type: CPC-II (Second Generation) Current Pressure Converter (Electro Hydraulic Converter)
Core application: Oil pressure control of single acting servo mechanism for steam turbine/water turbine, receiving 4-20 mA commands and converting them into stable oil pressure, achieving closed-loop control of valve opening, speed/load
Key features: redundant input, self-cleaning rotary valve, PID pressure control, fail safe oil return, status diagnosis, 11 point linearization compensation
Adaptation system: Woodward 505/2301A controller, 800xA DCS and other turbine control platforms
Supply voltage 18-32 VDC (nominal 24 VDC)
Steady state current of approximately 1.5 A @ 24 VDC
Peak current 8 A (continuous for 100 ms)
Input signal 2-channel redundant 4-20 mA set value (can be master/slave voted)
Input impedance standard 250 Ω (industrial universal)
Output control electro-hydraulic pressure regulation, driving single acting servo mechanism
Control algorithm with built-in PID and adaptive, millisecond level response
Linearization with built-in 11 point flow/pressure linearization table
Fault safety fault/return oil in case of power loss, valve to safe position
Diagnostic function input health, pressure sensor health, device health, alarm output
Configuration/communication support Woodward PC service tool, parameter calibration, diagnosis, trend recording
