VAC D500 Advanced Digital Positioner

Reliability-proven rugged technology-vibration test specied.

Flexibility-various mounting & options-SIL 2-ESD-analog or binary

feedback-alarms-micro-switches

Diagnostics-pressure sensor option for advanced diagnostics

Performance-Very high resolution, air delivery, precise positioning.

Simple-push buttons for auto-calibration & conguration,

LCD-program with standard loop calibrator.

The D500 microprocessor based positioner brings the latest technology, exibility, and

user-friendly features (local push buttons and LCD display) to the operation of a pneumatic

actuator and/or control valve package. A robust (Nema 4X, Ip 65) design, with excellent air

delivery, uses very traditional and proven components to provide very fast, accurate, and

consistent control with very low air consumption.

Optional accessories like analog or digital feedback, various switch options; an emergency
shutdown module, SIL 2 approvals, “fail freeze” option and pressure sensors for advanced

diagnostics make the D500 a “complete positioner package”. Coupled with VAC’s multiple
drive adapters and extensive list of rotary or linear actuator mounting, this “combination”
offers users and distribution channels a lot of exibility and opportunities.
