VAC V200IS

The V200IS electropneumatic positioner is used where Intrinsically safe (IS) applications are required or accepted. Intrinsically safe circuits utilize a safety barrier, located in a non-hazardous location, in conjunction with the V200IS positioner. The V200IS has approvals for CSA and FM.

Just as for the V200E the V200IS can be converted from a V200P, just by adding the basic internal IS IP converter module, at time of order or in the field – simple and effective.

The V200IS accept the traditional two wire, 4-20mA input signal via a safety barrier is available for use on rotary or linear applications. The V200IS utilizes a unique spool valve, is a cam characterized, forced balanced instrument that is simple and rugged. The V200IS have a pre-calibrated internal IP which uses the actual supply air pressure, filtered through a specially designed filter. The IP converter then converts this pressure via an electrical signal to a 20-100kPa / 3-15psi signal back into the positioner signal diaphragm chamber for mechanical positioner response.

With a rugged IP66 / NEMA 4X die cast aluminum housing and an electrostatically applied polyester coating the unit has an excellent protection against a wide range of environmental conditions.

Standard features like the external zero and span adjustment makes this positioner very user friendly for calibration and maintenance. The large indicator has scaling to operate in both direct and reverse directions. With the unique snap in drive shaft design the unit can be used for versatile mounting to various actuator applications. The gauge block is cast into the housing and therefore standard. Options like special cams, dome indicators and more are available.
