Product Overview
The WOODWARD 9907-1200 CPC-II CURRENT TO PRESSURE CONVERTER is a high-performance electro-hydraulic converter produced by Woodward. Here is a detailed introduction to it:
I. Product Overview
Function: 9907-1200 CPC-II is an amperage-pressure converter, used to control the inlet valve or related servo systems. It receives a 4-20mA current setpoint input and provides an accurate and stable pressure output proportional to the input current.
Application: This converter is typically used in conjunction with the Woodward 505/505E controller governor to control equipment such as industrial steam turbines, small grid turbine generators, or turbine expanders.
Technical features
High precision control: CPC-II can precisely control the oil pressure to accurately position the single-acting steam turbine speed control valve, thereby achieving precise control of the steam turbine speed and load.
Enhanced dynamic performance: As the second-generation current-pressure converter (CPC-II), 9907-1200 has enhanced dynamic performance, which can better adapt to rapidly changing load requirements.
Easy installation and maintenance: The CPC-II end face can be combined with various supports, and the installation and maintenance process is relatively simple.
Solves the oil contamination problem: CPC-II solves one of the top reliability issues affecting the normal operation time and performance of the equipment, namely oil contamination, thereby improving the reliability and service life of the equipment.
Installation and Connection
Adapter Kit: 9907-1200 needs to be installed on the adapter block (or board). The adapter block will connect the three hydraulic ports on the CPC-II to the external oil supply, hydraulic discharge, and valve servo control device.
Installation Requirements: The screws should engage with the threads of the CPC-II for at least 16mm to achieve a reliable and secure installation. The interface should be designed with a blind hole to accept the face-sealing O-ring.
Hydraulic Connection: Ensure that the hydraulic ports are correctly connected to the system: S connects to the hydraulic supply, C connects to the servo control pressure, and T connects to the hydraulic discharge.
Key Features：
Multiple relay functions in one device
Programmable logic capabilities
Communication interfaces for integration with other systems
High reliability and durability for industrial environments.
