VAC D400 Digital Positioner

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
good ltered air and proper maintenance, can provide very accurate and trouble-free service for many years. Available with HART,
FOUNDATION Fieldbus, or Profibus communication, the D400 range of applications and communications meets the latest
industry standards. The “efciencies” 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.

Features and Benefits:

• Microprocessor based valve positioner

• User friendly, menu driven programming with LCD Display-multilingual

• Local push button conguration—no handheld device or PC necessary

• Low air consumption and proven dependable mechanical design

• Modular design—available with position feedback, micro switches and “Fail Freeze” options—rotary or linear mounting.

• Aluminum Housing—Nema 4X IP 65 Enclosure—Standard—Electrostatically dipped varnish with stove-hardened epoxy resin.

• Unique adaptive control feature offers the ability to update valve/actuator package for maximum control without upsetting the process.

• ATEX-FM-CSA-IEC-Ex approvals available

VAC D400 Approvals

The D400 digital positioner has approvals for the below agencies. The details and exact listings associated with these approvals are quite
extensive. We have a supplemental document, entitled D400 Approval Details on our website under the D400 downloads or we can email or
fax you a copy. They can also be found in the VAC Manuals on our website under the D400 Product Tab and the far right drop down menu.
Even the listing between no communication and Hart units vs. Fieldbus and Probus can be slightly different.

All D400 unit’s enclosure are Nema 4X IP 65, Electrostatically dipped varnish with stove-hardened epoxy resin.
