WOODWARD 9907-1200 Pressure converter

Description

Woodward 9907-1200 is a high-precision electric pneumatic current pressure converter. Its core function is to convert 4-20mA DC input signals into proportional 3-15psi pneumatic output signals, serving as a reliable bridge between electrical control systems and pneumatic operating equipment.

9907-1200

This conversion process has high accuracy, minimal hysteresis, and excellent repeatability, ensuring that the output pressure accurately reflects the input electrical signal. In industrial automation systems, it can seamlessly integrate with programmable logic controllers (PLCs), distributed control systems (DCS), and various sensors and actuators. The two-wire design of this converter simplifies the installation process as it only requires two wires to achieve power supply and signal transmission simultaneously. In addition, it adopts a universal installation design that can be flexibly installed in any direction without affecting its performance. The Woodward 9907-1200 also has built-in diagnostic capabilities that can quickly identify potential issues such as signal loss or pressure abnormalities, which helps reduce downtime and improve the reliability of the entire system.
