WOODWARD

The Woodward 9907-1228 Current to Pressure Converter (CPC-II) is a device used in industrial control systems to convert an electrical current signal (typically 4-20 mA) into a proportional pneumatic output pressure (3-15 psi or 20-100 kPa). This type of device is commonly used in process control applications to interface between electronic control systems and pneumatic actuators or valves.

Key Features:

• Input Signal: 4-20 mA (standard industrial control signal).
• Output Pressure: 3-15 psi or 20-100 kPa (adjustable based on application requirements).
• Accuracy: High precision in converting current to pressure.
• Construction: Durable design suitable for industrial environments.
• Mounting: Typically panel-mounted or direct-mounted to equipment.
• Adjustability: Often includes zero and span adjustments for calibration.

Installation and Calibration:

1. Mounting: Ensure the CPC-II is securely mounted in a location free from excessive vibration and temperature extremes.
2. Electrical Connection: Connect the 4-20 mA input signal to the appropriate terminals.
3. Pneumatic Connection: Connect the output pressure line to the actuator or valve.
4. Calibration: Use the zero and span adjustments to calibrate the device so that 4 mA corresponds to the minimum output pressureand 20 mA corresponds to the maximum output pressure.

Applications:

• Process Control: Used in industries such as oil and gas, chemical, power generation, and water treatment.
• Valve Control: Converts electronic control signals to pneumatic pressure for operating control valves.
• Automation: Integrates with control systems to automate processes requiring pneumatic actuation.
