The Fairchild T9000 Series Electro-Pneumatic Pressure Controller has a closed-loop, integrated, microprocessor control system that regulates outlet pressure. The Model T9000 controls pressure in proportion to an analog electrical input signal. An internal feedback sensor monitors output pressure to achieve high accuracy. You can control the output from the Model T9000 using the keypad or from an analog control signal. You can control the output from the Model T9000D using the keypad and through DeviceNet™ Communication network. With its integral booster sections, the T9000 series of I/P pressure controllers delivers high accuracy at flow capacities of 1,6 m3/h in the T9000, 144 m3/h in the T9020, 176 m3/h in the T9040, 353 m3/h in the T9060, and 1123 m3/h in the T9080.
