D400 Digital Positioner Brochure

Product Brochure



The VAC D400 is a microprocessor-based, “intelligent” instrument that can be mounted to rotary or linear pneumatic actuators for accurate positioner control. This unit, while sophisticated in its accuracy and performance, is simple to mount, calibrate, and with well-filtered air and proper maintenance, can provide very accurate and trouble-free service for many years. With local push-button calibration and LCD, no expensive handheld devices are needed for basic set up and calibration. Available with Hart, Foundation Fieldbus, or Profibus communication, the D400 range of applications and communications meets the latest industry standards. The “efficiencies” of the D400 are not only in its microprocessor-based technology and accuracy but also in the pneumatic air handling where air consumption is kept to a very minimum.
